What does punching your teammates constantly throughout the match achieve?

@DaDeDimson
Also at the beginning of Arena matches, I am trying to use my cool new emote and they just keep punching in order to cancel mi animation >☹️

On the other hand, I had this problem on BR this season, I was looting a deathbox in fragment and my teammate just punched me and I fell off to the lava. Some people are just toxic and have 0 spirit of playing as a team, it's just disgusting.
