A very risky maneuver when you go out on the swamp and find yourself a gator. Once you get on that gator, you risk your tootsies by dangling them over the mouth hole of that gator.
when there's no handle or handrail to grab on a bus/train/tram, etc., so you're kinda riding it to prevent your falling onto fellow passengers
Man, I got stuck in the middle of the bus left without a handrail to grab so I had to do some busboarding, otherwise I would have ended up on one of them sweaty people
Bob: Hey, buddy! How was your weekend?
Buddy: Oh, you know. Just hanging ten on a southern surfboard.
Bob: Damn. How many toes did you lose?
Buddy: surprisingly, only 2. Garry Gator is getting used to me.
