Cottage Cheesing 

Cottage Cheesing is when you suck off an old guy and then spit the cum into a jar, let it harden, then chisel it out and smoke it. Then as your smoking it, it runs down your throat giving you a warm sensation throughout your entire body. It is called "cottage cheese" Because as it's settling in the jar it resembles cottage cheese.

Guy #1: Hey man, want to go cottage cheesing?

Guy #2: Sure I know where a bunch of old guys hang out, it's a great spot!

Guy #1: Awesome! I'm starting to run out of cum!

Guy #2: Ya me too!

cheesing 

A word that went from 2 definitions to 37 definitions on UD in just one day. Thanks to Trey and Matt.

South park aired an episode where Kenny got high off of cat pee and they called it cheesing. Now every South Park/Urban Dictionary freak like me has to add his/her/it's definition.
