Worst player grief you’ve ever seen?

Just played a match, we were winning big like 9-4, coasting through, seems like an easy win.

Player on our team one round on defense frags 5, gets the ace secured. Goes to defuse the spike, Sova on friendly team shock darts and kills him, lets the spike explode and throws the round.

Tilts the entire team instantly, enemy team comes back and wins 10-13.

Gotta love it.
