The act of having fellatio performed on you whilst sitting in a chair or laying on a surface in which your ass is hanging off the seat and simultaneously taking a creamy “peanut butter-esque” bowel excretion that can be caught in hand by the performer of fellatio, the feces are then used as grease to finish you off with a hot hand jibber and blow your white goblins all over your navel.

A racial slur meant to denigrate people of African descent. Though its origins are impossible to trace, it is most used in rural areas in northern Louisiana and may have arisen from the stereotypical racist depiction of the African American as perspiring and unbathed. Though, ironically, it has been shown that poor whites are more likely to have poor personal hygiene.

Compare to porch monkey.
Racist: "Yesterday on the bus I had to sit beside a grease monkey. It was gross."
