When you've been wearing over-the-head headphones on big hair, like an afro, for some time, part of your hair becomes much lower than the rest. Now you've got headphone hair and may or may not look weird.

When you sculpt your hairstyle around the on-ear headphones your wearing. The effect of such hair is ruined when the headphones are removed.

Subsequently, you look a bit of a penis.
