Gobble Flop 

The act of bouncing ones hanging testicles off a woman's neck while receiving oral sex making it look like she has a turkey gobble.

On a hot summers eve last year Andy proceeded to gobble flop his lady down by the pond, midway through they ended up sticking to her neck.

Receiving a deep throat from a trashy girl, she swallows your seed just as you back out a massive turd which falls into the toilet making the plop sound, a bit like the blumpkin but better.

Had a trashy girl the other night, gave me the best gobbleplop ever.
