look up any word, like the eiffel tower:
Sound made, usually by a woman, during the act of fellatio when the penis is repeatedly crammed deep into the throat.
Dude 1: How did your date with the hot chick from marketing go?
Dude 2: It was awesome! She practiced her Duck Call on me!

A very noisy, prolonged fart. It produces an artificial quacking noise similar to a hunter's duck call.

Such farts are produced by expelling a tremendous amount of gas quickly. They are uncomfortable, and do not attract ducks.
Damn! That duck call sounded like it blew your ass out!
