blowfish 

The act of pressing ones lips against a transparent surface, typically a glass window, to form a seal and then breathing out to expand the cheeks.

Generally the intention is to disgust or taunt anyone that may be on the other side of the window. Although slightly less offensive, the action is performed in much the same manner as to chuck a browneye.

"Quick, Sally's in her car, do a blowfish on her window!"

"Haha, blowfish!"

Describes the face a girl makes when you nut in her mouth and it expands her cheeks, making her face resemble that of a blowfish or pufferfish.

Trista offered to suck me off, and that bitch looked like a blowfish when she refused to swallow afterwards.

Getting a blow job while in a hot tub, or any other form of water. To be defined as a blowfish, the girl's head must be completely submurged under water, except to come up for air of course.

Girl: Wow this hot tub is nice.
Blowee: Yeah it is, have you ever given a blowfish?
Girl: No, what's that?
Blowee: I'll show you, here's a snorkle.
