J-killa

Subject Of the poem "The Greatest" by Robert Riemer, J-killa got his name from his many feats of heroism and sexual mastery on the streets where he grew up (he is legally married to Kate upton). He has served as chief advisor under Abraham Lincoln and FDR, and is rumored to have written the Gettysburg address on a roll of toilet paper while he was taking a dump somewhere in Pennsylvania. His most astounding accomplishment, however, was undoubtedly his victory over Heavy Thway in a contest of length (j-killa's penis won by a margin of over 8 feet). In 2014, j-killa was preemptively elected in the presidential election of 2032.

"This is a great man. I love him."-- John Lennon

J-killa is a fucking boss
