The act of pulling on a girls hair with both hands while having sex from the rear and screaming hee yaww and shaking your hands up and down . This often results in a very unnatural wave of the females hair that can be spotted by everyone post intercourse.
JOHN: Damn, why does her hair getting so messy.
DOE: That is because she is getting a quick "Pony Pull" in the back.
JOHN: What a wh*re.............. Id still hit it.
