I just made up a new language.  It's called Z-Drippy, and it will be the official language of my new nation-state, Diet Pepsi.  Diet Pepsi will officially exist as soon as I can get PepsiCo to sign some paperwork.  In the meantime, why not learn a few phrases?  And because body language is 70% of communication, I've included some rudimentary gestures to help you along:
Where is the toilet?    Z-drippy toilet? (cup crotch with both hands, hop from one foot to the other)
Can I exchange money here?  Z-drippy money?  (squint, pound fist on table)
How long will my flight be delayed?  Z-drippy delay? Delay? Delay? (flare nostrils rapidly)
I need a doctor. I have a sliver in my foot.   Z-drippy sliver? (sit quickly, remove shoe, point to foot)
I would like a double room.   Z-drippy DOUBLE ROOM.  (jab index finger into receptionist's lapel)
How do I get to the beach?  Z-drippy beach?  (smell hand with keen interest)
I'll have the salmon corn cakes.  Z-drippy! (point to item on menu)
I'm an American.  Z-drippy?  (point to self, bare lower teeth only)
I'd like a cool, refreshing Diet Pepsi.  Z-drippy cool, refreshing Diet Pepsi.  (rest forehead on table)
