On your machine it probably means the monitor profile, or whatever profile the device should have. Besides what happens when we eventually deprecate sRGB as a general standard? So if the image is not for web store the images defined working space and dont convert it until you need to if you want to retain as much data as possible.
PS color profiles are a very convoluted idea i would be careful saying you understand them. Maybe say you understand the general concept instead. Sign up to join this community. The best answers are voted up and rise to the top.

Ok, it seems completely sensible that I don't need a color profile for web-destined images. For example, glossy paper is capable of displaying a different range of colors than matte paper.
By assigning, or tagging, a document with a profile, the application provides a definition of actual color appearances in the document. But when tagged with the Adobe RGB color space, these numbers specify an actual color or wavelength of light—in this case, a specific color of purple. When color management is on, Adobe applications automatically assign new documents a profile based on Working Space options in the Color Settings dialog box.
Documents without assigned profiles are known as untagged and contain only raw color numbers. When working with untagged documents, Adobe applications use the current working space profile to display and edit colors. Profiles describe the color spaces of the input device and the document B.
Profiling software can both calibrate and characterize your monitor. Characterizing your monitor simply creates a profile that describes how the monitor is currently reproducing color.
Brightness and contrast The overall level and range, respectively, of display intensity. These parameters work just as they do on a television. A monitor calibration utility helps you set an optimum brightness and contrast range for calibration. Gamma The brightness of the midtone values.
The values produced by a monitor from black to white are nonlinear—if you graph the values, they form a curve, not a straight line. Gamma defines the value of that curve halfway between black and white. Phosphors The substances that CRT monitors use to emit light.
Different phosphors have different color characteristics. White point The color and intensity of the brightest white the monitor can reproduce. When you calibrate your monitor, you are adjusting it so it conforms to a known specification.
Once your monitor is calibrated, the profiling utility lets you save a color profile. The profile describes the color behavior of the monitor—what colors can or cannot be displayed on the monitor and how the numeric color values in an image must be converted so that colors are displayed accurately.
Note : Monitor performance changes and declines over time; recalibrate and profile your monitor every month or so. If you find it difficult or impossible to calibrate your monitor to a standard, it may be too old and faded. Most profiling software automatically assigns the new profile as the default monitor profile.
For instructions on how to manually assign the monitor profile, refer to the Help system for your operating system. Color profiles are often installed when a device is added to your system. The accuracy of these profiles often called generic profiles or canned profiles varies from manufacturer to manufacturer. You can also obtain device profiles from your service provider, download profiles from the web, or create custom profiles using professional profiling equipment.
To embed a color profile in a document you created in Illustrator, InDesign, or Photoshop, you must save or export the document in a format that supports ICC profiles. You can embed a color profile in an object or an entire PDF. Acrobat attaches the appropriate profile, as specified in the Convert Colors dialog box, to the selected color space in the PDF.
For more information, see the color conversion topics in Acrobat Help. There are very few situations that require you to change the color profile for a document. This is because your application automatically assigns the color profile based on the settings you select in the Color Settings dialog box. The only times you should manually change a color profile are when preparing a document for a different output destination or correcting a policy behavior that you no longer want implemented in the document.
Changing the profile is recommended for advanced users only. Select this option only if you are sure that you do not want to color-manage the document. Working [color model: working space] Assigns the working space profile to the document. This is the safest guidance for the purposes of most users. Member Offline Posts: Andrew Rodney.

MarkM Sr. Safari's interpretation of untagged at least in OS This means that even in a well calibrated environment untagged sRGB images can look awful on monitors unless the monitor space happens to be close to sRGB.
Mark Meye. Thanks Guys Mark: You are right - they look awful on Safari on a wide-gamut display. That is what made me notice the difference with my exports from LR and Save for Web from Photoshop; the Photoshop saves were bad! Now I am embedding the profile they are almost the same as LR's Phil.
