Roasted Colon

The anatomies of when you launch a firework rocket out of your asshole but then back fires and blows your ass up like the results after geting a hand grenade vigorously rammed up your arse

Ps. you tuck the firework in the wrong way...

John: HOLY FUCKING NIGGATRON!! (see Niggatron) i just got a Roasted Colon after having a rocket up my arse following by five lit katherine wheels :) :) :)
