hair shirt

a garment to induce some degree of discomfort or pain as a sign of repentance and atonement

My brother sinner, even though I completely understand your need for purgation, there isn't a man among us with half a conscience who doesn't keep a hair shirt as a permanent part of his wardrobe.

hair shirt

When a hairy guy shaves his upper arms right below the cuff of a short-sleaved shirt. When the shirt is removed, his hair resembles a hair shirt.

'You're swimming with your shirt on?'

'That's my hair shirt asshole!'
