Putting a fresh banana in a microwave and setting it for 10 minutes on high. The after effect is a burnt phallic shaped object that smell's like a yeti's ball sack.
I skated out of work early, but before I did I went to the accounting department's breakroom and left them a black johnson. TGIF mofos!

Mos Def's rap-rock band. You can hear Black Jack Johnson on the song Ghetto Rock which is on Mos's album The New Danger.
Person 1: Yo, did you hear Mos Def started a band?
P 2: Yeah, Black Jack Johnson, I heard he did it because he says that Rock bands have no soul like Limp Bizkit.
