"By Odin's beard" I've heard said before..
Thrall's Balls! From World of Warcraft. Thrall was the leader, until recently, of one of the two major factions in the game.
I stick to the saying I first heard Bender say on Futurama. Oh your god.
The most religious I get with my exclamations is "Sweet zombie Jesus!"
I like Bender's but he is so confrontational. I'd like to use that with christians. Litmus test though is my grandma.
Holy random chance Batman!
Help me baby cheeses!
Oh no - I love using these and elaborating them
"Jesus Christ shit the bed and had a haircut", "Christ on a windsurfer" or on special occasions "Jesus c*nting Christ" I have used on occasion, mainly as it really pisses of Theists. You have to remember the more hardcore, the more they hate blasphemy which to me is a carte blanche to exercise my militant atheism and ridicule them.
So yes you could say religion has influenced my language :o)
Would you say these things to your lovely great aunt who doesn't like a potty-mouth?
Nothing I'd use in polite company...
Oh c'mon, spill the beans!
