When you are face fucking a chick, pull out after you fill their mouth with semen, then proceed to slap both of their cheeks at the same time yielding the same appearance of a whale surfacing for air.

When someone is sleeping and you croutch over top of them, pull down your pants, place your butt cheeks close to their face, then slap them across the face to suddenly wake them up and cause them to jump up into your ass....if a well executed white whale is performed the nose will directly hit the anus. Note: the person giving the "whale" is white (caucasian), otherwise it is known as a "black" whale (or substitute according to ethnic background and ass color)
My college roomate was sleeping on my couch, so I decided to give him a white whale.
