Nalg 

Short for "Nalgene." Nalgene's are expensive, indestructable 32 oz. water bottles, often used for discretely transporting alcohol around in public.

Me and my friends are going to Nalg it up at the pool tonight at midnight for my birthday.

nalgarhythm 

A compound word formed from the spanish word "nalga," meaning cheek and the english word rhythm, which describes motion or movement.

Nalgarhythm describes the movement of the posterior, specifically the cheeks.

I don't even like those stupid spinning classes. The only reason I go is to sit in the back and peep that sweet nalgarhythm.
