This is calling back to a song from chance the rapper’s 2019 debut album, The big day and particularly the song, hot shower.
These are the first main lyrics used by chance to convey to the listener. That he has muscles like Superman trainer. This means to the person who says this that he has muscles from the hero, Superman and also from a trainer, particularly an athletic one.
“Hey Jim”
“ I got muscles like Superman trainer”
“ oh you must be strong, me to”
A person who enjoys obliterating others taints. One who lives for the meat highway between asshole and the balls. Not afraid to get dirty and get some scat between their teeth. Always ready to feast.
Damn Dave is such a taint destroyer. No wonder he always has hairs stuck in his teeth and shit on his nose
