Well, I'm never doing that again.

I beat Green grass and high tides on Rock Band 1, guitar, expert, solo. I will never be able to do that again.

Just remembered, in a game of Nazi zombies, round 12ish, all my team mates died near the beginning, and I ended up winning the round all by myself.

This one doesn't work very well on me, either.

in one of the tekken games I used Paul and he did an attack that hit once but took away 75% of the opponents HP. I think it was a glitch

Burning fist. Push back from the opponent and both punch buttons. One of my favorite moves. Only drawback is charge time.

Halo 3 on Sandbox. I was on the side of a Hornet and my friend was driving around on a Mongoose and I managed to headshot him from the top part of the map (Excluding the Sky Bubble). You can't use a scope on the side of a Hornet.

I was stuck at a level of the rapture world in Super Meat Boy, I just couldn't make the jump.
So after lost of failed attempts I put the game down and didn't thought about it for a few months.

Until I got home on a Sunday morning in a intoxicated state. And for some reason I decided that I would try one more time.
Somehow I rushed through the game and nailed most of the jumps in one try.

And till this day I can't replicate the speed and smoothness that I had on that intoxicated morning

I got 3 killing sprees in 1 game of Halo: Reach on Powerhouse. I think it was simple team slayer, so not multiple rounds to do it in.

I felt like a god. Then I went and got crushed underfoot next game.

A couple of awesome MvPs in Halo 3, one including a perfection.

On the subject of Halo 3:

My friend and I were playing through the campaign for the first time on Legendary. Being the nerds we are, we had the Star Wars Soundtrack Anthology playing on my laptop. As we ended the first level, where you detonate the Nuke, the soundtrack for the first movie was ending.

The part where the Death Star is about to fire, but then it explodes instead was playing as we rushed into the elevator.

Start at 10:55 and imagine that is when you rush into the elevator. Right as the Death Star explodes, the music crescendos. Right as the music crescendos, the Nuke went off on screen, and we both looked at each other, our jaws agape, and then busted out laughing. Sure, it took us an hour to beat the first level, but the incredible timing was beyond worth it.

That's the 2nd level, actually. Well, 3rd if you count the opening cutscene (which is its own level). I'm sad enough to have played the campaign through about 7 times, I know these things.

In Battlefield P4F, I sniped a helicopter pilot and killed the copter, pilot, 2 gunners, and some poor sod who was trying to get up the ladder to my camp site. 18K/1D in that game.

Managing to get 5th place in a race with an unmodified Fiat 500 in GT2 still sticks with me

Apart from that, just ain't good enough to have such moments more than about once a decade

Was playing tekken (the one with jinpachi mishima as the big boss) and i managed to down him on hard difficulty without taking any damage, i was like "How the fuck did i do that "

During a 45min long attempt to get my friend the "If they came to hear me beg" achievement in reach (assassinate an elite from a lethal fall).

We jumped off the cliff, my friend undershot and died. While I landed perfectly... on top of the elite taking no damage and stayed there for a few seconds before it got pissed and ran around.

I played Black Ops once, first time in the CoD franchise but I was definitely not a noob at that stage.
What surprised me, though, is that one time I was playing on Nuketown. Doing amazingly good, topping the scoreboard at about twice what everyone else was. The game was almost over and I got booted and banned by the admins online at the time.
And that was a server I played regularly - sure, never was that good before or after, but I surprised myself that I managed to get banned with such little effort when I usually suck!

Easy.

SSX on Tour and I managed, no idea how, to snowboard into two poles. At the same time. Yes, it's not possible, but I did it.
