ambidrinksterity

The ability of being equally adept to drinking from each hand. Wikipedia says this about a similar word, ambidextrous:

"Studies have shown that ambidextrous people are more emotionally independent, more determined, more adaptable to new situations and more apt to handle problems without giving up." -Wikipedia

Therefore, one can conclude that ambidrinkstrous people are also more emotionally independent upon drinks, more determined to drink with both hands, more adaptable to new drinks and more apt to handle problems without giving up drinking from both hands simultaneously.

Cinderella & her ugly sisters entered the ball. Quickly, Cinderella was handed two drinks by two different gentleman, because she ONLY had two hands, and because her ugly sisters were scaring away the others. Cinderella, a bit tipsy from the champagne in the carriage ride, burped and muttered, "Hmmpf. I'm ambidrinkstrous..."

The gentleman were all in agreement, ambidrinksterity was a great quality in a young lady.
