hair boner 

when a girl with short hair puts her hair in a ponytail such that it resembles a male erection or boner. this is the only time a woman will ever or should ever sport a boner.

"damn, your hair boner just hit me in the face."

"is it just me or is your hair boner more voluminous than usual?"

"i like your style. that hair boner is hot."

What every University of Michigan fan has right now.
