verb. when people are bored, they do this type of action which is RANDom, and is also a crappy greetING. As you can see, i capitalized the two words combined to make randing in the sentence before this. Anyways, such as some people just randomly go like "sup" and dont say anything important. Pandar personally thinks that is retarded, to talk to someone when there is nothing to say. So he developed this word so people would stfu about that crap. Sometimes, when they even say "sup" and you say "sup", they concut you by saying "nothing", i mean if they want to talk, can they be more social? which proves the panda's fact of these corrupted dickfaces.
Somone (not gonna say who): sup
*after 3 minutes*
ThatPandaNigga: ....uh....k..? so thats all you're gonna say?
ThatPandaNigga: DUDE ARE YOU BEN-ED? YOU JUST RANDING'ED ME, CAN YOU AT LEAST BE A LITTLE MORE SOCIAL IF YOU WANT TO TALK?
Someone: sorry, i was busy
ThatPandaNigga: WTF...?! so you're busy and you all of a sudden say "sup", do you just want more IM's or something to look cool? i mean thats not even cool anymore, that's like super gay. just stfu soul.
