What is the dirtiest thing you have done to a friend?

@E9ine_ACnothing much actually, but I don't know if the following is considered dirty.
placing a jump pad, launching my teammate in the air near the edge of the map which he barely survived then drop inside the ring ( ring no:4) during a fight with the last two squads in a ranked match 🙂

it was by mistake ....uhm ... I swear 😇
