Las Vegas Oil Change 

When a man fucks a woman/man's mouth while simultaneously shitting on the chest of the fellatio performing participant.

Jimmy's girlfriend was giving him head while Jimmy had a serious case of the runs (too much cheap beer). At one point Jim could not hold it in and in the middle of the mouth-fucking, let his bowels loose all down his girlfriend's chest; giving his partner her first ever Las Vegas Oil Change.

Rose Oil 

Oil from rose flowers. If you sniff it you'll get high, but not hooked and you'll lose weight. Easy way of life! Just like saying better than Gucci!

Slacker Dude: Aw! Man! That exam was hard!

Smart Dude: It was rose oil for me, because I studied everyday for six months straight!

Kuwaiti Oil Rigging 

Giving someone an enema of crude oil, putting a stopper on their anal cavity and puncturing a hole in the stopper guzzling the oil as it escapes the anal cavity at a high velocity.

Dude, last night was crazy; my wife gave me a Kuwaiti Oil Rigging, we're still cleaning up the mess.

Mexican Oil Change 

The act of one man walking up to another man, sticking two fingers in his butt, and kissing him on the mouth. Most often used in prison as a way to assert dominance.

On your first day inside, walk up to the biggest guy in the pod, and give him a Mexican Oil Change. Show everyone who’s the man!
