similar to derr, but more dumb. especially if you use it on msn. pretty much a noise you make if you want to sound like a doofus, or are just being a moron, or want to aggrivate your friends, or are really, REALLY, stupid.
1. stupid kid (on msn) - derh. i dunno.
other kid (on msn) - hehehehe lol
2. kid - yeah, you know that kid? he says "derh," like, all the time.
other kid (being accused of saying derh) - wtf are you talking about? no i don't, asstits.
A slap to the face, often from male to male, used sometimes to intimidate, anger, or irritate. Mostly, however, this term is for quick revenge for someone saying something dumb. At the same time, the word "dummy!" is shouted, characterizing the victim.
1: First Person: I rammed your momma last night. Second person: Dummyslaps!
2: I'll dummyslap you!
3: You dummy. *Slap*
