When you're full cock down a chicks throat and she starts to quack on it, but you leave it that deep down her throat and stop moving like you're buffering so she chokes and quacks even more.
Duude, I pulled a full duckbuffer on my girlfriend last night when I made her deepthroat me. She sounded like she was one quack away from being an Aflack commercial.
