Putting ones finger in another's anus to "check their oil". Checking their fluid/solids level to be sure they are not to low or high.

Hey babe will you check my oil? (Said girl)

Oil Check

When you stick your finger up someone's asshole checking for poop, while saying "oilcheck".

oil check

An act whereby an individual inserts his finger or penis into the asshole of another. Much like an oil check on a car, the appendage can then be examined to determine whether or not the contents are clean or dirty.

I saw Sam with his back turned to me so I gave him an oil check.
