T.I.

You know about me, dog

Don't talk about me, dog

And if you doubt me, dog

You better out me, dog . . .

Know you don't like me 'cause

Yo' bitch most likely does

(From his 2006 hit, "What You Know."  Later in the song, T.I. says "all that attitude's unnecessary, dude."  But T.I. probably has more attitude per cubic inch that any other rapper out there.  One final note: my bitch does like T.I., and it really pisses me off.)
