Sugma is a
pun/play on words
It is related to
ligma, and bofa, but all three can be traced back to updog.
A person will say something
like "it smells
like updog in here"
Then someone else will say "what's updog"
Then the 1st person will say "not much sup' with you?"
But for ligma, and sugma people will say "did you hear about the
guy that died of (insert 1 of the 2)?"
Then someone else will say "what is (insert 1 of the 2)?"
Then the 1st person will say "(insert 1 of the 2) nuts!"
Bofa is the same but instead of (sugma or ligma) nuts!"
They say "Bofa dees nuts!"
Most will be followed by a "ha got'em!"
