Pissfart. One of the many insults that are allowed to be used in roblox. Pissfart means a smelly little crusty musty dusty pigeon looking ass pissbaby. Pissfart is when u piss and fart at the same time, so it sounds like a queef and it smells, which is the best description for that 8 y.o. little roblox kid that called you a noob .
“dude!! that kid called me a noob for having no robux!!”
“dayum he a real pissfart”
Peter could no longer control his bowels during the job interview and did a pissfart which formed an embarrassing brown stain on the back of his cotton pants.
