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

Get the Hairline mug.
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."
