The worst type of pain. If someone tells you that they hope you hit your ankle on a scooter, they most likely want you to die. You are highly recommended to stay away from people who have ever said that to you, or anyone you know.
Arvin: I hope you hit your ankle on a scooter!
Mikael: *runs away, moves to another country*
It's a way to express vulnerability even during success.
Originally stems from fighting games to express frame advantage.
Use it in daily conversations please... do it
Example : Newborn
Parent A : "James we finally got a child !"
Parent B : "Yes Susanne but it will have no legs !"
Parent A : "guess he is -3 on hit"
