When a warm breeze blows. Specifically when flatulence is emitted in the midst of a rim job.
The rimmer that Misty gave me last night was so good that I gave her a Chinook.

To those making sexual definitions about this, you are the most retarded dudes I have ever met. A Chinook is a heavy, dual rotored transport helicopter that has a top speed that is almost 200 MPH. Primary use is to transport infantry and/or vehicles. In Call of duty they have replaced the little bird helicopters for the care package delivery. it is slower and is a bigger target in BO so one can shoot it down and steal the package.

Me: aw yeah, got the care package

enemy: *shoots down chinook*

Me: you son of a bitch!

A happenstance in intercourse where the woman is on top of the man, where the rhythmic thrusting causes the woman's breasts (and therefore, nipples) to rotate in a circular pattern, like the twin blades of a chinook helicopter.
