Reverse Jiffy Lube 

A hybrid of the popular reach around penis grab. This occurs when a female reaches between a males legs from behind and begins to grip and rub the penis. Done over clothes and results in a penis erection. Usually done as a mating ritual to see if the male "sizes up" so to speak.

Jenny is giving Earl a reverse Jiffy Lube. That lucky S.O.B.

Tokyo Jiffy Lube 

When you take a massive steaming shit in a Japanese bitch's ear in order to lube it up, and then proceed to fuck said orifice mercilessly, while speaking to her in Japanese. You then jism deep in her ear, possibly causing loss of hearing from the excess of jism.

"Last night, I gave Sakura a Tokyo Jiffy Lube."
"Oh, really, did she lose all hearing in her ear?"
"Yes, she did. There was far too much jism and fecal matter for her tight Japanese ears to handle."
"There she is right now. Hey, can you hear me?"
"Nani?"
