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.

(UK) A descriptive term (n/adj) for the act/person when (usually ) a lad has penetrative (vaginal) sex which lasts only a very few strokes before he ejaculates, either because of inexperience or desire to achieve insertion then move onto next girl/target. Likely the girl does not achieve orgasm
Most of my college party experiences were hop ons
