when you put gravel(large gravel, like 2B size gravel) into a girls butt and then proceed to have sex and cum in her butt. after cumming the girls swishes the gravel and semen mix and shits it out onto the floor where you are waiting with a trowel to mold it into whatever you so choose, preferably a yert.
"Wow, he sure gave her a great cement mixer last night! Just look at the size of the yert they made!"

A common name for a porno, though a cement mixer is a special type of porno where body parts are arranged in incredible artistic arrangements....like when you get a flower arrangement and they make em all pretty.

A foul joke/prank performed. While perturbed, you take a dump inside a laundry machine dryer thats filled with your white laundry. You then run the dryer to 'mix the cement' and leave hardened skid marks on the victim's wardrobe.
