YSAMF 

Means "You Stupid a** motherf*cker".
Basically is just a ghetto version of "You stupid idiot!" But a bit more offensive.
(The non abreviated ver.) Can also be used for rap battles.
This type of word is commonly used for online communications such as "chats".

"You stupid idiot! That's so basic! YSAMF!"
