Osama Bin Ballin

Listen up, buttercup. This joke is funny because it mashes up "Osama Bin Laden," the dude behind 9/11, with "ballin'," which is slang for playing basketball really well. Get it? So, it's like saying a Muslim basketball player is super awesome, but using a name that's, like, totally infamous. You probably still don't get it, because you probably main ADC.
