I keep noticing this term 'looser' being chucked about as an insult...where does it come from? Is it like, 'your mum's looser since I ****ed her'? Or 'Your sister's been looser since she took it up the wrong 'un from an elephant'?
I am obviously not down with the kids, so if someone could explain why blokes are calling each other loosers I'd appreciate it.
