To simultaneously penetrate both the vagina and anus with two clenched fists.

The use of two weapons, one in each hand, during combat.
Can either be projectile or melee weapons.

1) To use two firearms at the same time. Popular in many action-oriented FPP shooters. But not the good ones like Doom, Quake or Deus Ex. Apparently rather ineffective in real life.
2) To use two one-handed melee weapons at the same time, rather than one weapon and a shield. Seen a lot in all kinds of RPGs. Probably would be effective in real life if mastered, but seems like no one ever bothered to try.
3) To stick one fist into the girl's baby hole and the other fist into her poohole.
4) To jerk off two cocks at the same time, wielding them akin to clubs or swords. A display of great multitasking, passion and ingenuity.

Also known as akimbo or dual-fisting. The act of firing two guns at once, one in each hand.

A ridiculous, idiotic, and downright fucktarded practice popularized in John Woo movies and unrealistic video games like Call of Duty.

It is probably descended from the few gunhands in the old West who used two pistols. But instead of firing both at once, they would either do a Border Switch (draw two guns, empty the first one before firing the second), or a New York Reload (draw your backup piece when your weapon runs dry rather than reloading). This is because it is impossible for a human being to look through two sets of sights at once.

Therefore if you fire two guns at once, at least one of them won't be aimed at all, causing you to waste all of the ammo in that gun hitting nothing that you actually wanted to. Or you could just do it the Hollywood way and not even try to use your sights, meaning you'll just spray & pray with both weapons, waste all of your ammo, and hit everything except your target. Also, using two SMGs or automatic rifles instead of pistols doesn't make this stupidity more effective, it just makes you waste more ammo, look more retarded, and still not hit jack shit.

Whilst in the act of consuming alcohol, one who is dual wielding will be holding two different bottles. One bottle containing alcohol, of course; and the other being a good chaser.

Good examples are:

Rum and Coke.

Vodka and Orange Juice

and for all you hicks out there; A 40 and a bag of pretzels.

People who are inexperienced at drinking can not dual wield. It's completely impossible and is frowned upon by the elder drinkers in the room. No one likes a sloppy dual wielder.

However Dual wielding does a fair amount of skill, if you want to get really pro and do work like a man, throw the chaser on the ground and pound that alcohol.

this is mostly done by black people. it is the act of having 2 phones; one for texting which is usually a t-mobile sidekick and the other is usually a nextel or sprint
