Monkey Wrench 

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!
