Informal. Greeting. Colloquial version of "What's crackin'?", with the added bonus of being nowhere near as white as asking "What's cracka-lackin'?".

A way to ask someone what's happening in their life, and popularised by the song "Take a step back" by Ski Mask The Slump God and XXXTENTACTION.
"Yo, what's frackin?"
"Kevin I really wish you would stop saying that."
