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.
Person 1: Haha, jake was dual wielding last night like a pro.
Person 2: No shit man, he has that steez
down to a science.
Person 1: (*dual wields* and hands both bottles to friend)
Person 2: (*slaps person 1*, ignores the chaser and drinks like a fish)
