hair bruise 

The strange, mildly painful and "bruise-like" sensation that results from letting one's hair down after pulling it back all day with a headband or into pony tail.

If you didn't pull your hair back so tight you wouldn't have that hair bruise when you take out your pony tail.

Prickly Purple Hair bruise 

The Prickly Purple Hair Bruise is when your girl is getting ready to ride you during the nasty and your dick is resting upward along your lower belly and she start rubbing her pussy lips along the underside of your dick, thinking you enjoy it. Meanwhile her needle-like shaved coochie hair is scraping your shaft like using a bristle brush to clean grease off of a flat top griddle, causing excruciating pain that feels like it's turning your cock into minced meat. The next day you we wake up with a purple dick, because not only did she unknowingly apologize for torturing your helpless little pecker by fucking you like a Jack rabbit, but tried to turn your Johnson into a Bloody Mary.

Alex: "Fuck, my dick hurts"
Chris: "Why?"
Alex: "This bitch rode me mad hard last night after rubbing her serrated VAGINA all over my Wang. I got that Prickly Purple Hair bruise"
Chris: "Damn bruh, that's a hell of a way to pop your cherry"
