Disco Charades

Trying to converse in a bar or club playing high volume music means having to shout loudly into one another's ear at close range. This problem particularly affects the young, cosmopolitan singles that chat offline in deaf-defying clubs in the world's metropols.

I suggest the establishment of an international set of gestures to convey the most common phrases such as:
"Do you come here often?" (form U with upturned hand + walk with the index and long fingers in the air several times + point towards floor)
"Your place or mine?" (clasp hands as in prayer while on knees + place them under the head tilted sideways + point index finger alternately at observer and self)
"Does your 'no' really mean 'no' or can it mean 'yes'?" (make windshield wiper motion with index finger + raise shoulders and eyebrows + stick long finger deep into mouth + peel an imaginary banana).

Not only would the vocal cords be spared, but a new dance craze might be born from long conversations.
