WATCH OUT! WE GOT A BADASS OVER HERE!

[Nalbis]

There's a fair few, top 3 has to be:

35+ yard free kicks in Fifa 12 and 50+ yard goals as well (at the moment these are the ones that make me a little bit tingly inside)

Single/Double-tap headshot in Counter-Strike against someone who is in the better position (also flick shots)

Landing perfect C-Viper/Ryu combos in SF4AE resulting in a perfect. (Always makes me feel like Daigo)

Minigun, no medic, enemy spawn.

Alone.

Come at me. I ain't dying for the next 15 minutes as far as I'm concerned.

Suiciding a landing Dragon in Skyrim and ending up defeating it by sheer luck with a Longsword randomly lifted off the ground in panic, resulting in a finishing move that made me feel like my last stand was something that would be sung about in Taverns for years to come.

Also, Ballistic Fist kills in New Vegas. When it goes into Slow-Motion for the Legion Assault on that last poor Raider... Oh God yes...

And every time I go back onto Modern Warfare 2 with my Riot Shield to fight some friends. Them standing tossing grenades and spraying, bullets whizzing past my ears as explosions go off all around me, only to leap at them and turn them into paint on the walls. Every Time I can't help but grin and imagine my own little Soundtrack in the background.

Skyrim
- That one rare finishing move as a werewolf where you grab someone by the head and throw them at the nearest wall
- Going outside to find THREE dragons in the sky trying to get at you (bonus points for using your dragon call shout for a total of 4 bad-asses in the sky at once)

Metroid Prime 1
- Walking into a new area and grabbing 3 missile expansions in under 15 seconds.
- The wavebuster hack in the Ridley battle (Only works in the Gamecube version unfortunately)
- That one cutscene after beating the Omega Pirate (GC version)

Majora's Mask
- Binge drinking Chateau Romani when you have too much money to waste.

Pokemon
- Walking through Mt. Moon without encountering a single zubat.

Portal 2
- Speedrunning so that the loading screen sessions are longer than the actual playing sessions.

TF2:
- Shanking every player pushing the cart within a timespan of 2 seconds (spy)
- That one moment where someone blasts epic montage music over the mike and your winning ability goes way up.
