Little baby stack farts
The most lethal and noxious gas that comes out of a man/boy that looks like Jimmy Neutron while he's in a deep slumber. They smell like exit 13A in NJ, mixed with a homeless man's shit. They are usually accompanied by giggles. Little baby stack farts can't kill you but you'll wish you were dead.
Omg. Ew. This room smells like tiny little baby stack farts!
