Freebie blow job, unreciprocated oral sex.
My girlfriend is on the rag. Maybe I'll get a blowbie tonight!
In her internal combustion engine, blow by is not easy or cheap and requires the continuous movement of hot pistons to push back and forth in the cylinder wall in order for it to happen.
HotPiston BlowBy happens when we ignite my girl's Internal combustion engine air and my HighOctane fuel. My explosion makes its way to her crankcase through the piston rings and orgasmic blow-by occurs, every time.
Action in which the man spreads ass cheeks and the girl places her nose in his asshole and simultaneously inhales as he releases his blowby poot.
"Dude, I killed my girlfriend with a nasty blowby poot last night."

When you have to shit really bad and you fart resulting in the fart blowing by the dookie in you asshole. It also leads to a horrendous smell in the room making people think you shit urself.
Oh my god Kyle do you have dookie blowby or did you shit your pants. Lay off the Taco Bell and monster man!
