Not a gay mc, I'm straighter
My style is similiar to AIDS
You can f with it now
But catch you later
You can't touch this, cuz this is what I'm feelin bro
A mildly homophobic sequence of rhymes, though this wouldn’t have rated as very offensive in 1994.
The gay/straight wordplay in the first line is a bit crude, and plays on the double meaning of straight as both “heterosexual” and “functioning at a high level.” Cf. Kanye West’s similar (but less offensive) line on We Don’t Care
The gay reference prompts a reference to AIDS, which in 1994 was still thought of as a largely “gay” disease — AIDS is sexually transmitted, meaning you get it by fucking. Similarly, even if you “fuck” with Common’s style (try to challenge or disparage it), after some time has elapsed you will be forced to admit that it is superior to your own (Com may be implying that you will go so far as to mimic his style).
“You can’t touch this” encodes a Hammer reference, but also continues the preoccupation with gay sex. You can’t “touch” his style, meaning come close to it, because it is what Common is “feeling,” i.e. it is a style that Com loves, and has labored to perfect.
