Tramp Scab
The end bit of a sliced potato that still has it's skin on, that's been made into a crisp and found it's way into a bag. Usually about the size of a thumb nail.
(gets passed a sharing packet of crisps) "Oh, great, you've had all the best ones and left me just the Tramp Scabs!"
tramp scab
scab on lower back from falling trying to do backside 180s.
did you see those nasty tramp scabs on marc johnson's back in the fully flared video? I guess that's the price to pay to pull out those backside flips like he does!
