Pebblenash

The act of desecrating the toilet due to an over reliance on protein shakes and excessive time in the gym (without any focus on sphincter muscle exercises).

Darren Fletcher is known to have routinely pebblenashed the toilets at Old Trafford, that's why he's no longer in the team.

Fucking hell Nash, you been on the Maximuscle again? The bogs have been proper pebblenashed, you dirty bastard.
