Butt Breather

A person who still smokes in 2025

The term draws from the 2025 “butt breathing” (enteral ventilation) human trials, where scientists tested delivering oxygen through the rectum to patients whose lungs could no longer function properly.
“Quit hacking up a lung, you butt breather.”
“Don’t queue up yet, the butt breather needs his smoke break.”
“Even with all the new research and treatments out there, he’s still a butt breather.”
“She says she’s quitting next week — classic butt breather line.”

You inhale it all, nuff said.

Riah: Dont tell me he’s into feet or something
