In the online game series called “Halo,” CS was exposed to the start of a long running insult to one’s opponent called “tea bagging.” The movement, crouching up and down over a dead enemy, was so infamous that it got its very own name.
This action of crouch spamming over an opponent that the player killed, has since expanded to pretty much all online shooters, but is less often called by the name. Instead, the action is by far the most recognizable part of the gesture.
When playing the online game “Overwatch” with CS, he got killed and “tea bagged” by the enemy team.
Disrespect and crude humor is a common occurrence in online video games, especially when it gets very competitive. The same way that basketball players might taunt each other before and after making shots, online gamers treat the sport with a similar attitude. With more and more humor coming from the internet, on occasion, this emote/crouch spam taunting makes its way even into the material world.
I found one other post about this online taunt/humor in our archive:
