Haircaine 

A very thin line of pubic hair of a woman that sits above the vagina. It is very narrow like a thin line of cocaine. Much preferred by strippers and other sex workers.

Man, did you see that strippers haircaine? I almost rolled up a Benjy and snorted it right on the main stage!

Among us hairline 

Only the most elite members of society are seen with these. It is a privilege, but also a massive responsibility to have an among us hairline. The among us hairline is a symbol of leadership and superiority, which is why you have never seen one, for holders of the among us hairline do not show themselves amongst average human beings.

Bro got that among us hairline, damn.

Fucked Up Hairline 

When your hairline looks awful or ghastly.
This may even cause others who see it to have a nauseating effect due to witnessing such an atrocity.

Drew aka Drewbacca perfectly exemplifies this definition:
His hairline resembles a staircase, now this wasn't done on purpose hence the "Fucked Up Hairline"

Hairline 

The line where your hair starts. For some reason, dumbasses like to make fun of people's hairlines when they don't really matter.

Kid: U HaVe a rachet hairline!
Sane person: Why does it matter?
