All the other definitions had it wrong so I decided I'd put mine in there.

A lesser known variant of the popular "69" where a girl is giving birth to a baby and she sucks your dick while you make out with the baby.
A doctor had 68 with his patient in the delivery room and was promptly fired when security footage of the incident was discovered.

it's simple: blow me and i'll owe you one, i.e. like a 69 except i just wanna get my dick sucked without performing oral favors for the sucker (cunnilingus, analingus, or fellatio)
jimmy wanted to 69 with me but i didn't feel like licking out his scuzzy hole or suckin' on his lil' boy penis so i just let him suck me off and we called it a 68
