abbreviated form of 'wassup' which derives from "What's up?" Used as a general greeting or a brief 'how are you' by people who are too hip for full sentences.
Yeah, I know I posted this like a few weeks ago and if you scroll down you can find it but the link doesn't work anymore and I'm too lazy to change it. I remember when I was first watching it i remember thinking "WHAT THE HELL IS ACTUALLY THERE?" cause everything just fit too perfectly. At first I thought it was a little kid or something but some parts I was just like ??????????????????? SO mystery solved.
