When a girl is grinding on a guy on the dance floor and accidentally leaves a pee stain on his pant leg. Similar to a snail trail.
That chick was totally getting me hot on the dance floor until she left a lemonade slide on my pants!

Two dicks in one hole thus the shafts of each penis would have to touch. The gyrating motion of sex would cause each shaft to slide past the other. This issue can happen on purpose or accident.
Micah and Tim were banging Cindy one in the pink and one in the stink when Micah slid out and instantly joined Tim in a sliding trombone

When you snowboard up to a rail, but don't jump high enough to get on it, causing you to fall backwards and slide down the rail on your back.
"Dude, did you see that? I just grinded that rail on my back!"
"A spine slide?? That's more impressive than a real grind!"
"A spine slide?? That's more impressive than a real grind!"
