backwoods oil change

A sexual act while your sexual partner is tied up in BDSM fashion, inserting 2 large black dildos into both the vagina and asshole simultaneously while vigorously thrusting the male appendage deep into the throat of your completely vulnerable partner.

So I saw this video the other day of this guy giving this girl a backwoods oil change, probably going to run it by the ole lady later this week. Total domination bro..

My friend Johnny Runescape told me about the time his girlfriend gave him a seaman Oil change. Says his balls have hurt since.

Oil Change

The actual of taking a dumb while, or shortly before eating, effectively draining the old substance to add in fresh product.

Person #1: You gonna get off the dumper and eat those pizza rolls, or you just gonna let them go cold?

Person #2: No, just a routine oil change. Gotta empty it out before I fill it back up.

Oil change

The act of chugging water while urinating. Typically in the middle of the night after a long day of drinking too much.

I drank so much yesterday, but I’m not hungover. Probably because I did 3 oil changes in the middle of the night.

Oil Change

An oil change is expressly defined as changing out one’s inner fluids; this means peeing, shitting, and then cumming consecutively. The best way to start off your day.

“Hey Johnny, have you finished your daily oil change yet?”
‘Not yet man, I still haven’t finished my number 3!’
