A classy move where a girl is giving you a rim job and you rip a huge fart into her mouth. Her cheeks puff up and then she's the Baltimore blowfish.
I hear your mom works in Baltimore. That must be pretty tough on your family.

This is an act in where your significant other is eating out your asshole and then you proceed to fart inside their mouth forcing their checks to puff up like a blowfish. Then your significant other then proceeds to blow that fart back into your asshole!! If done correctly there should be a slight whistling sound!
