Get the yo dipmug. Ya-yo is slang for drugs , more specific CRACK. It is a street term. The only effidence I could find to support this was it used in a song written by Ice-cube called Once Upon a Time in the Projects. check out some of the lyrics. The nigga said "yo, what's for sale"
and the bitch came out with a bag of ya-yo
She made the drop and got the 20 dollars
from a smoked out fool with ring around the collar
The girl I was waiting for came out
I said BITCH I DIDN'T KNOW THIS WAS A CRACK HOUSE
and the bitch came out with a bag of ya-yo
She made the drop and got the 20 dollars
from a smoked out fool with ring around the collar

Get the ya-yomug. One way to insult someone is by telling something false of their mother, as a form of negative comment.
Hey, that kid who was older than me, said some mean things about my mamma because I had $50 and he had $10. He said "Yo Mamma is so ugly, when she looked out the window, she got arrested for moaning.". What should I do? I didn't do a thing wrong!
