I find that a shout weird things while I play video games such as if I'm attacked by Cuccos a shout with a weird accent,"I am being attacked by pollo/poyo.(the spainish word for chicken) I also name certain patterns odd things such as the "anal passage" in Bit. Trip Void.

i probaubly say the F word when im screwed

I find myself saying alot of choice words when playing VVVVV or Super Meat Boy. I also refer to the Barinade boss in Ocarina of Time as Tentacruel alot.

"Damn were dah nekit cheat codes".

I once growled "PIKACHU" at random intervals during a match of MW3.

I always drop the F bomb when I play Call of Duty with my friends.

"Not again..."

"You suck!"

"Whatever."

"****ing Mario..."

"AAAAHHHHH!!!!"

"Wow."

"Nooooo!" or even my personal favorite right before I know I'm going to die: "No, no, no, no, no!"

"Amazing... Absolutely amazing."

come on, guys, surely we can all come up with weirder things we've said while playing video games than plain ol' F-bombs, can't we?
_{though i've been known to drop more than a few of those myself at times :3}

D:< That's it.

"Ooooh Raiden nice @ss!!!"
"Vamp is so flexible. I wonder what he's like in bed."
"Did that deer just crap itself and go flying while doing so? WTF."
"Well I know what I'm doing tonight."
"Is that a guy?"
"Hahaha it's humping your face."

I better stop before I get myself banned.

"Come at me bro!"
"There's no such thing as bystanders!"
"You should totally shoot that guy"
Guy explodes"I think that guy might be dead"
I tend to say the weirdest things when I play Saints Row the Trird with my friend

I also find my language to become more crude when I play Kirby! lol
I also seem to cuss out Pacman a lot, too.

Glad you asked...

So my cousins were over, and I was playing Skyward Sword (haven't touched it since, sadly). I went to Beedle's Airshop and started talking him. My cousins started to make fun of the way he says "Oh!" every time you go up to him. They said this word over and over, and it got stuck in my head. I switched to Star Fox Assault for GameCube (terrible game BTW), and started the story mode. During one of the "cutscenes" someone goes, "We need a mechanic, STAT!" and then a random toad says, "I'm a mechanic!" at which point Slippy goes "...Dad?" somewhat hilariously. We had fun mocking this for a while until I had the brilliant idea of combining to the two phrases to give birth to, "Oh, Dad!" That is now my personal motto in life, and has, for obvious reasons, been coupled with a father saying to his son, "I'M A TATER." to which his son replies, "Oh, Dad!" It works both ways, with the son revealing that he is a potato to which his father replies, "Oh, Son!" I really hope you didn't take the time to read all of that.

Because this is a family site I can't really say here but I am sure you can imagine.

Other than that about the weirdest thing I yell out is when I play my paladin in WoW and I do a move called rebuke which interrupts spellcasters I say "Roadhouse" like Peter Griffin in that one episode of Family Guy when he goes around kicking everything, because the original animation for rebuke was a kick.

Often I'll say, "derp derp derp DERP DERP!" over and over again while frustrated.

come on mario jump F higher man

i just passed stage one of streets of rage now that trill there

D bison cheat come on ken

just tourettes guy refrences, one of my favorites "OH Bob Saget"

excellent choice, sir! I have been known to imitate the tourette's guy as well :3

the thing i often say is "UGH, COME ON!"
this happened a lot against one of the boss in skyward sword (robot-like monster with 6 arms... i hate it ._. )

I often talk to myself when playing Mario Kart. The most common phrases are:
"Oh my ___ god."
"Are you kidding me?"
and the always-charming,
"I don't care where I finish, I will kill you."

Aside from the usual unintelligible and/or profane expressions of frustration, a couple of the two more bizarre:

I sing the word "banana" over and over again to the Super Mario Galaxy theme. It fits strangely well. Ba-NA-na ... Ba-NA-na ... Ba-NAAAAA-na ... Ba Naa-aaa-na ...

This one goes back to the NES days — when playing my cousin in the Vs mode of Trojan, we somehow started shouting "CHEESEBURGER ON RYE!" as a battle cry — always, always, whoever invoked the battle cry first inevitibly won. Today i will occasionally still invoke the "CHEESEBURGER ON RYE!" battle cry when in a rough boss fight.
