I like this

God bless you. I use that as a curse word. Most don't catch it.

A good "fuck" always feels good.

I like the C word, but it's not socially acceptable and someone inevitably runs out of the room, either crying or clutching their pearls.

Goddammittofuckinghell is my preferred expletive.

"God dam it" seems to come out more often than anything else. Deepens on the situation I guess.

Fuck, number one!

GOVNYUSHKA - it's a Russian word meaning something covered in shit and used as a sled. There's just so much weirdness packed into that word, beginning with what conditions led to its creation in the first place!
When my kids were younger, I tried to curb my outbursts around them. Expressing frustration by near-musically uttering/repeating "BLYAD'" (FUCK) around the house seemed pretty safe. Sighing, "YA YEBU" (something akin to "well, fuck" ) is also pretty much a staple

Goddamn-motherfucking-sonovabitch, why choose just one when they all run together so well?

bollocks is my current favorite.

I hate the word "cunt". But love the word "thundercunt". First heard it on the show, "Weeds".

Different ones for different moments.
Injury: Fuck
Mistake:god damn it
Seeing something shocking: oh shit!
Seeing something mean or idiotic: mother fucker
Seeing trump do something well: Holy shit.

Twat.

Fuck

Either " fuck me gently with a chainsaw" or " Jesus fuck me". Depends on the situation.

Twatsicle

Depends on the circumstances. Different profanity for different situations. Anyone who disagrees with that can eat my ass.

See how that works, motherfucker?

"Hostie d'câlisse de sacrament d'tabarnak!"
We French speaking Quebecers have a really weird way to swear. Instead of sex related curse words, we use religion related words. Words from the Catholic vocabulary tweaked in the local Quebecer accent. It may sound absurd, but if someone around here bangs his bare toes on a bed leg, it just comes out!
The most notorious "sacre" is "Tabarnak", which comes from "Tabernacle", "A case or box on a church altar containing the consecrated host and wine of the Eucharist."
There is "Hostie" which is the host, the sacramental bread, "Câlisse" (Chalice), "Sacrament", "Calvaire", "Ciboire".
So much that the Quebecer tourists traveling in Latin America (Mexico, Cuba, Dominican Republic) are called by the locals "Los Tabarnacos"!

good old versatile anglo saxon FUCK
fuck you, fuck me, fuck that, fuck it, fuck off

Motherfucker

Not wanting my kids to hear me when I worked on the car, etc, I created my own: Ubiquitous Whore. Aside from that fucking fuck fucker.

Weener, especially weener dog for a frustrating individual. I frequently sprinkle my speech with more prosaic obscenities too.

I quite like the term 'cockwomble' but rarely use it. My most used has to be twat.

Damn 

Shit

Bloody hell!
