Do you have a word/phrase to say instead of swearing?

When people let out anger we always say ''fuck'' or ''shit'' or something of that sort. 
 
I have tried to change that, while I have nothing against swearing if I get mad in public I don't want to start yelling ''FUCK'' randomly. xD. 
 
So do you have something you say to substitute it? I have a really nerdy one that I say as a habit, but it is embarrassing. xD Here is mine-
 

SON OF AN IRISH DOG RIDER
 
it's not technically a swear

I'll say 'effin' or 'eff'. Like, that game was effin' hard.

'Frackin'- Bloody Battlestar Galactica ;)

I occasionally say "sin," though not really as a "substitute" for anything. I just say it as if it were another exclamation. Like, "Sin!" and "Aw, sin."

fuck the people who care if you say fuck.

Futha Mucka.

FROG OFF!!!

Usually I'll just go off and swear outright, but certain company requires more tact. As such a family favourite of saying 'Armpits' is employed. Occasionally, this will be upgraded to 'Armholes".

Cocksucker?

yeah I say Frack as well

"FUCK!" 
Wait. I guess that doesn't count.

i'll usually say eff, but that's about it. i'm foul mouthed 

I sometimes say Eff. Or use fudge although that is rare. I don't have a problem swearing. Most words other then Fuck can be used without too many problems. Besides cunt of course.

fuck no, cunny funt

Shi-
Sshhtuffing!

When I almost say "fuck" I say "whorebag" instead. Works great.

"Ducking" instead of "Fucking" occasionally, assuming the cursing is to be worded comically. "Feth" and "Fething" from the Gaunt's Ghosts books have also stuck to me in some fashion.
 
Aside from these I curse like normal. After all, when someone is being a cunt, he should be called a cunt. Exaggerated profanity can sometimes be hilarious, if used correctly.

Futher mucker or FARGE!!! or piss out my ass!

After hearing it on QI, I've started using "Hells bells and buckets of blood!". It's more an exclamation of annoyance, but I love it.

"What the foxtrot?"

BLOODY HELL or Sod it!

No not really i tend to just take a deep breath before i finish my swear, "Oh for fu....." and relaxed. But im usually quite happy to swear in public although i rarely get angry.

" "FUCK!" Wait. I guess that doesn't count. "

For fun, I say "holy cheese and crackers" in place of "holy shit".

"mother fussbudget"  & "poo"  Anything funny since it helps alleviate some of the tension I'm feeling at the moment.

I follow in Father Ted's footsteps... Feck

"Gorram".

fuuuuuuuuuuuuuuuuuuuuuuuu

Not really but I say "fudge" instead of "fuck" sometimes because of my stupid humour.

" Feck "

Schnell.
 
It sounds like a swear word!

thunderpunt. 

Fuck

Bosh'tet!

Been saying "jeeze" instead of "shit" recently because of TV edits.

There's always the "frick" and "frack" substitute words and the saying "Son of a Biscuit!" 

My fav...WHAT THE FRUIT!! 
 
Haha Classic XD *nods*

I usually say, madafakka or mafakka instead off motherfucker.
 
But usually I just swear.

I seem to be using Derp a lot lately.

I say 'Rats!' if need be. But I wish I would say 'cuss' instead.
 
I love Fantastic Mr. Fox.

Funt. It is a combination of the two greatest swears.

All of this
