The act of two males spreading their butt cheeks and trying to make their butt holes touch by backing into each other.
John: What's that sound? It's like someone smacking two Easter hams together...
Seth: Oh, that's just Ben and Mike monkey wrenching in the other room.

The person being 'wrenched,' as the kids like to call it, takes a big water jug (like the ones for water coolers) and shoves the mouth of the jug into his/her ass. Once the jug is inserted the person does a hand stand, letting the water flow freely into his ass. Often done as a practical joke. A hand stand is not nessisary in joke form, you may just tip it over and let the person enjoy!
-We 'monkey wrenched' Allan last night, he got really pissed off!
-Look at Osama, he's so drunk he's doing a 'monkey wrench' right on the table!

When a woman gives a man a blowjob, and before the man ejaculates, she twists his member clockwise in a wrenching motion while he attempts to ejaculate.
I was hoping for a good time with that prostitute, but she ended up giving me a Portuguese monkey wrench.
