whaddit look like whaddit do 

derived from c-murder (not the rapper, the dishwasher/hustler)-it simply means how are you doing

"whaddit look like whaddit do!?!" legitimate response would be-"whaddit be 'bout!?!"

Whaddey 

When you don’t feel like texting “What did they” or “What’d they” so you just combine the two because you are lazy.

Person 1: Did you ask the boss about coming in tomorrow.

Person 2: Yea.

Person 1: Really?! Whaddey say?
