Get the whats hannenin mug.
the title of the most annoying song ever produced under the genre of "hip-hop" by none other than the (opinion) worst rapper ever, Soulja Boy.

ghetto way of saying Whats Happening, which means whats up.
Soulja Boy: "whats hannenin whats hannenin whats hannenin whats hannenin whats hannenin whats hannenin whats hannenin whats hannenin......"

Drake: Yo, nothin much brotha, jus seein my girl with her sweatpants hair tied chillin with no make up on...and by the way I think i got tha question the first time you said it.
