68

When a person attempts to engage in the act known as a 69 with a frozen being made of snow (i.e. a snowman). Fair warning to persons of whom may be intrigued by this activity, it is very important to wear protection while 68’ing.

“My daughter’s Frosty The Snowman was looking so fine, so when she fell asleep I went and 68’d the shit out of it.”

“With a nose like that, I’d 68 Olaf in a heartbeat!”
