A sink that collects cum from December -1st till the end of October, once No Nut November (NNN) arrives, the cum inside the Cum Sink will be left to thicken into an exquisite stinky cheese that will be harvested at the very end of November in time for Destroy-Dick December (DDD).
Gary: Hey bro have you harvested your Cum Sink yet?
Jarred: Not yet, I prefer my dick cheese to be thicker like Philadelphia, that cream cheese that goes well with crackers such as Cheddar.
An okay replacement for a Cum sock if the laundry hasn't been done. Although may lead in to some confusion.
P1: Hey sorry i was really thirsty so i drunk your milk.
P2: What milk?
P1: You know, the one on the desk.
P2: Oh my god.
P1: What do you mean?
P2: That was my Cum Mug.
P1: WTF!
P2: This is what happens when you don't do the laundry Steve!
