twenty one sixty

$21.60 is the price of a cheap 12 pack or a 26 oz bottle of liquor .. the term "twenty one sixty" can be used to refer to the girls easy enough to split a 12 pack, or a 26 with, and get them to suck on your nuts.

Works good on your CB radio, if you're a truck driver, a police officer, firefighter, or a HAM radio operator .. btu who the fuck has a HAM radio anymore ???
