checking the oil level

Putting your finger in a woman's vagina to see if she is wet

I was checking the oil level on lisa lastnight it was a little low

Dropped my oil pan

To take a sudden, massive, hellacious shit of EPIC proportion. Usually spontaneous, sudden, unexpected, and embarrassing.
Imagine your colon as an overinflated balloon that just got popped!!

"Man!!
I should have known not to have eaten those Atomic pork rind nachos, hot wings, and beer...I woke up at 3:00 A.M. with a stomach ache- If I wasn't as fast as I was, I would have dropped my oil pan in the hallway on the way to the bathroom!!"

Tuning Oil

Used in southern Appalachia to describe white liquor (moonshine), because the shine will get you "tuned in"!

Give me a horn of that tuning oil, man!

Oil Glazing

Topping a dessert with a woman's cum. See Jizz Topping for when it's a man's.

His cupcakes seemed rather boring still gave it an oil glazing.

Oil On Wood

Telling someone that they are like "Oil on wood" is like telling someone that they are beautiful and that they stand out in a good way. Putting oil on wood preserves the wood and makes it stand out more so when you say that someone is like "oil on wood" is like telling them that they are preserved and that they look outstanding.

"Oh you look like oil on wood today"

"Wow this dress on you is like oil on wood"

oil neck

Any person who no life's runescape that isn't from a foreign nationality

Corrupt idea no lifes runescape therefor he is an oil neck.

slap oil

When you slap a person so hard the oil from their face comes out onto your hand!

I slapped that bitch so hard the the slap oil from her face screamed in my hand!
