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 ???

Yo, that bitch is a total twenty one sixty.

sixty-six

Originally appearing in The Complete Sex Dictionary (1969), the "back door" cousin of sixty-nine, sixty-six is a euphemism for anal sex.

"Okay, clue in me in. How'd it go last night?" (Snicker, snicker).
"It was the usual fanfare: we sixty-nined for a while, did the nasty, but ended up in a sixty-six."
"Lucky dog. She really MUST love you."

The act of driving at 65 mph on a road with a 70 mph or higher speed limit and thinking that you are speeding. Very common in the state of Texas.

SixtyNinety

The sexual act where, two persons simultaneously engage in tonguing each other's anus, while facing each other's front. The change from the traditional 69 position from double genital stimulation to double "o-ring" pleasure dubs this act "6090".

My girlfriend and I tried a SixtyNinety to spice things up and boy was it spicy!
