Statistics say that niggas with no father ain't going to be shit
Well I guess I had one because nigga I'm it
You smell that? That's the odor of success bitch

from Tyler The Creator – Inglorious Lyrics on Rap Genius

Meaning

Statistically, black men with absentee fathers tend to perform poorly in school/work, and often end up in jail or dead

Tyler figures that he must have had a father because he’s “it”, meaning that he’s “the shit” (the best). Being “it” also implies that he was his own father (ie. he raised himself)

Tyler then goes on to adapt the well-worn “shit”/“the shit” pun (what up Weezy). Since shit smells, and Tyler is “the shit” (because his music is great and successful), the odor of his success is strong
