The Great Flood

[Edwardo Piet]

Bum, backside, ass, bum cheeks, fanny (US) ... "xxxx my arse" is a UK expression comparing whatever was said with "my arse" and in this context essentially means meaning, "you're having a laugh", "you're reaching", "you're insane", "you're deluded".

I think sometimes arse sounds better sometimes ass sounds better. For example I think "kickass" sounds better than "kickarse" (especially when Cartman from South Park says it). But I think "X my arse" sounds better than "X my ass" but it all depends, and depends what you're used to, and variety is good too.
I think asshole does sound better as something to shout, but I think arsehole is funnier.
Oh yeah and Daystar, you say we can't argue properly with scripture, but at least my argument regarding scripture is very simple and a very strong and direct argument: You can't use scripture as an argument from God! Valid evidence please!
