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?

Hairline 

When the corner of your hairline is receding so much so that it looks like a right angle.

Jake: "Oi bruv, are you losing your hair?"

Rhys: "What?!"

Jake: "Yeah bruv. It looks like a right angle in that corner."

Rhys: "You're right my hairline's fucked."
