Right after eliminating his former teammate, Dallas Fuel player Hyeon "EFFECT" Hwang yelled "fuck you xQc" without missing a beat on Widowmaker.
Both players were members of the Dallas Fuel before Felix 'xQc' Lengyel's departure from the League during the Inaugural Season.
The pair seem to get along pretty well, so this is probably more of a friendly jibe than any kind of malicious comment.
Defending on Dorado, Effect is poking around the enemy spawn as Widowmaker when he spots his gorilla opponent.
Honestly, xQc probably appreciates this level of candor from his opponents, since he's been known to supply plenty of his own trash talk.
What really matters, and what the clip doesn't show, is which team ended up winning the match, though that would probably do nothing to stop the smack talk from either of these players.
Effect returned to South Korea and missed out on Stage Four of the Overwatch League, but later announced he would be back for Season Two.
Since being dropped from the Overwatch League, xQc is still participating in professional Overwatch and will join team Canada's Overwatch World Cup team at the BlizzCon finals this November.
