Your dick stay chilly, it’s a cold, rough world
I get superhero pussy, she a PowerPuff Girl

from Childish Gambino – The Real Lyrics on Rap Genius

Meaning

“Your dick stay chilly,” meaning you’re alone without any chicks to keep it warm for you

The Powerpuff Girls are super heroes, so he is saying that the pussy he gets is literally from a super hero.

It is also a double entendre — the other meaning being that she “powerfully puffs”, a.k.a., gives him great head.
