Cumcrete 

Mixing one's cum with sand, cement, and gravel that creates a form of concrete with cum instead of water. Great for building, just not for one's family or friends.

Damn bro, y'all are using concrete to pave roads, while I'm using cumcrete. Yeah, I was banned from the sperm bank.

cumcrete 

After ejaculating, semen is left inside the urethra. After some time, this seminal fluid hardens causing disturbed urinary patterns.

I was aiming for the toilet but due to an excess of cumcrete I urinated all over my pants.

Dry semen left on a countertop after masturbation.

My roommate is a bastard. He left cumcrete on the bathroom counter by the toilet. I thought it was toothpaste until a tried to wipe it up with a wet cloth and almost puked from the smell.
