When, usually at the bar or a party, a guy (your buddy, unless your a total dick) goes for a broad, but you call out something that won't give him a chance. It's usually about an STD or him having a wife.
From, "You gotta slay a few dragons to get to the princess" a dragon slayer is someone who is out doing dirties with the hopes of finding a nice girl to really date. Or he's just using it as an excuse for never settling down.
"Gillies has been a dragon slayer longer than Jesus!"
"He'll never get to a princess"
"No way does he even want to!"
Afterdrunk - n.: The state of having drank the night before, experienced being drunk, and then somewhere in between sleeping, drinking water, choking down a perogy and throwing up, the room starts to spin, and you feel all the sensations of originally being drunk. (Minus out that wrench in your stomach and you could actually feel good about it).
Guy #1 "I was so afterdrunk in the AM that I actually told my girlfriend I'd take her to dinner."
Guy #2 "Let's hit the bar before lunch."
