1) The brief way of saying: "Hi, I'm really pathetic, what are you doing?"
2) Probably the worst response to any humane or initial greeting.
3) Okay if used when your under the influence, jocularly, and/or feel the need to be obnoxious for one hot sec.
1) Man sitting at bar with Corona: "'sup"
Woman trying to get a drink: "Oh! *Smacks forehead* I'm so sorry, but I don't understand all of the one word you just asked me or if it even if was a question at all"
2) Kind girl texting boy: Hey :) What's up??
Boy one hour later: "'sup."
3) Drunk tourist in cab: "Man, you do understand how epic tonight's gonna be, right?"
Hammered tourist friend: I know, dude! ETA 15 minutes... SUUUUUUUUUUUUUP ATOWNNN. We're about to Get It IN!
Sup is something cool people say. It can be used as a greeting. People say "sup" when they don't feel like saying whats up because it's to long. Also, people say "sup" because they get in the habit of saying "sup" so they just always say it. It can be used by girl or boy.
While our lifespan is the number of years we will live, our healthspan is the number of healthy years we will have and our sexspan is is the number of years we will continue to be healthy enough to continue having an active sex life.
A lighthearted reaction upon receiving disappointing news of some sort. Usually something that isn't a particularly a big deal, esp. when it primarily affects someone else - sort of a mild schadenfreude. Sometimes doubled or tripled, and possibly said in a sing-songy voice for added comedic effect to imitate a muted trumpet, which is how the meme originated.
