Plerchk 

The noise a car theif makes when you catch him breaking into your car and you hit him in the throat with his own baseball bat.

Me: What the FUCK?!?!?
Car Theif: <scrambles for bat> PLERCHK!!!!!!!

Plerch

Any spot on the body where semen can catch and pool.

The semen landed perfectly in the ass plerch on the top of Corina's asscrack, enough to drown her gerbil.
