seven ply enema 

when you're skateboarding and doing a flip trick or other critical maneuver and you land with the board standing straight up into your ass, sometimes it bleeds, thats why its called a seven ply enema.

dude, i was trying to kickflip the 10 stair and got a seven ply enema, it ruined my session.
