Edmonton Oil Change

When you creampie a girl and immediately after grab an oil pan and catch the cum as it pours out of her vagina. The girl then has the option to swallow the collected cum.

John: Hey man what’s up with your girl? She seems to be in good spirits today.
Max: Oh yeah man, I gave her an Edmonton Oil Change last night so she’s runnin’ like new today.

BROMINATED VEGETABLE OIL 

Brominated vegetable oil (BVO) is vegetable oil that has had atoms of the element bromine bonded to it. Brominated vegetable oil is used as an emulsifier in citrus-flavored soft drinks such as Mountain Dew and Gatorade to help natural citrus flavors stay suspended in the drink and to produce a cloudy appearance.

Oh look that soda looks like it has "brominated vegetable oil" in it.
