Tube Arse
The feeling you get after riding the tube or subway where you are walking round and you feel the need to wipe your arse because of a build up of sweat and moist bum dirt seepage. Often a safety wipe is recommended and the victim may leave behind a pale speck of bright brown tube arse.
"hey man, why are you walking so weird?"
"I have a bad case of tube arse i picked up on the way home from work, I better be safe with a safety wipe, have a date tonight"
