When you wake up the morning after a long night of drinking and realize that the person you took home is actually a lot better looking than you remember.
Mel: "The guy in my bed this morning was super hot!! I thought he was just average looking last night."
When you think a chick is attractive before drinking, but after you have a new perspective from alcohol consumption, she's not so hot.
Dude, I was waiting to get a little buzz before I hit on that chick but now she looks gross. I think I have reverse beer goggles, I need to be sober and desperate to hit that.
