Hop} [Ons are when someone hops onto your car that you are driving and rides around with you for awhile.

I was driving to work in my Stair-Car when I got several hop-ons when passing the corner full of illegal immigrants.

up ons

Shortened slang for "get up on this," which in turn means "have some of this." Generally used when offering to share something.

"I can't finish this soda. You want up ons?"
"Nah, I'm not thirsty, but thanks."

pig-ons

Short for pig on a spit. It is the act of one boy fucking a girl in the pussy or ass doggy style while she sucks another boy's cock. Taken to the extreme it is possible to lift her off the ground so it resembles a true pig on a spit.

Me and bill gave the slut across the street pig-ons last night.
