Firstly, as said by a fish called WandA (ooh sorry I mean a man called WandA, a man called WandA) the English way should be arse so if he was here I hope he'd appreciate the reference to arse rather than ass.
Either way, regardless of what you call your derrière now is the time to show it.
Now I know it's only 4 months since the last revolution of this type but we've had a lot of newbies since then and 'unofficially' a lot of lovely bums are gracing our avatars.
SO, get your cameras out and start taking pics of those lovely bums. And if you really don't like your arse, pinch someone else's! (Edited: If you do pinch an arse might be a good idea to say so - I don't want my self-esteem damaged with a dis-proportianate number of models arses gracing the forum LOL)
