I'm pretty sure I've read a similar suggestion in the past (can't find it), but here's the gist.
When you're rating somebody, it would be nice to have some "fun" tags that you can either rate your friends or even some not-so-great-friends w/ in a funny or sarcastic way.
Not sure if you guys feel the same but it may add a sprinkle of fun w/ a friend or even somebody who's completely ridiculous after the game has ended.
Examples of things that come to mind:
Dramatic, Slippery Goose, Delicious, Inebriated, Personality Plus, Buttsniff, Poser, Total Fail, Super Smart, Accidental, Sexual Dynamo, Lucky, Vivacious, Obviously Lonely, Me & His Mom are friends… etc (you get the idea).
I believe that this will make the site a bit more fun but while I realize that this shouldn't be at the top of the list or even close to it, although seems it would be a quick one to implement which is why it may be noteworthy. I may be crazy so let me know.
