Saying GG and Rage Quitting

  (Edited: )

Is it only me or are GG's and Rage Quits situational?  I find that in many games that I win, the opponent will sometimes BM about my race or just straight out leave without a GG.  However, in games that I lose, the opponents tend to actually say GG.  Heck, I'm guilty of this myself a lot of times.  So does anyone else do this or have noticed this before?  I personally find it kind of funny.
