Sometimes used as a title to some of these smaller people:
'Awwwww you're a munchkin and a half' (normally referred to a slightly taller munchkin/short person, therefore adding half a munchkin)
'You're the Munchkin of YAY!'
2) The best card game ever, along with Pimp: the Backhanding. Makes fun of number 3.
3) The most annoying roleplaeyers you'll ever have to deal with, who characteristicly max out their stats, mostly without reprecution, play to mindlessly kill anything in their paths and boss the rest of your players around, and get as many dots or levels as possible. Most don't really develope their characters' personalities.
b) I was playing a game of Munchkin the other day, and Frank, Jess and I all got to level nine and had to duke it out for the win. It was intense.
c) I swear, if _____ insists on making his new character another fraking munchkin, I'm going to be the ebil ST and either drop a celestial bouvine on him or force him to fight a fucking manticore within three games.
