A "plarp" is the noise that occurs when a person with a fat, saggy booty plops themself into a chair and farts.
Laqueefa's plarp made the people in the surrounding seats leave the area.

The sound made as feces is released into a pool of liquids
Man i dropped a load and it plarped at the bottom splashing water on my anal hole.
