Term originating in South Louisiana that involves slapping a girl in the face with your penis. While extremely similar to mushroom stamping, the "hangartner" requires one to cum in the girl's hair immediately after slapping her in the face
Dude! Did you see that chick with the crunchy hair and red marks on her face? She must have just been hangartnered!
