Me and my friends are "Those Guys" when we queue up in Destiny. I'm talking full on, dominate the enemy team in Skirmish and proceed to host a dance party until they respawn debauchery. It doesn't normally start off like this, but it devolves into that the second someone on the enemy team whips out a shotgun.
What sets us apart from other guys is the fact that we're not above exploiting game mechanics to win. For example, in Skirmish, you receive 50 points for reviving a fallen teammate. This means that, in close games and on maps that allow it, we can post up in a defensive position on the side of the map and have one person suicide and another quickly revive him for a free 50 points, because Bungie didn't think to put a suicide penalty into the game. If you're within 50-200 points of winning the game, its a hilarious way to close. If you're far behind, its impractical, but hilarious to watch the enemy slowly catch on to what is happening and try to stop you.
In our defense, months of playing Halo competitively did this to us.
