Having the ability or tendency to look good even when covered in sweat, dirt, overly practical/plain clothes, guts, or whatever life throws at you.

Carrying off the rough-and-tumble look, as opposed to looking like crap after doing something strenuous or dirty.
The opposite of 'cleans up nice'.

Similar to dirty stop-out, a dirty stop up is a person who is usually in bed and asleep early but is awake later much than expected.

A term used jokingly towards another person, normally used by people who are from Yorkshire in the UK.

For example when parents come home from being out for dinner and their children are awake after their bedtime.
"Oh you dirty stop up!"
"What time do you call this? You're normally asleep by now, you dirty stop up!"
