look up any word, like ratchet:
 
1.
a way to say shut up when you are bored. you say it with a flat tone. also, for people who are picky about language, you say shupup and they cant consider it a bad word cause it isnt. another thing is if someone is really bothering you, you say shupup noob, drawing out the noob.
"I'm checking my facebook, shupup noob!"
"shupup man, that joke sucked."
