Similar to a lap dance, but a girl rubes oil over her body. Usually with the accompaniment of music and lingerie. The girl generally ends up naked.
Jim: My girlfriend surprised me with an oil show last night.
Jack: Really?
Jim: Yar - she rubbed baby oil ALL OVER her body while dancing to music. She started in lingerie and finished naked.
Jack: Fuck, I'd love to see that - she's hot as.
The slobber and jizz on a dude's mug when he is done sucking a dick. (Typically used as an insult to describe a friend's face after they pig-out and have food on their chin, etc.)
Bob's grinning from ear to ear, his ugly mug glistening with Oil of So Gay...And he ate the last hot wing, that fat bastard!
