During a recent livestream where they played EA Sports FC 25 together, KSI and IShowSpeed agreed that the loser of each game would be on the receiving end of a whipping.
As shown in the archive of the stream above, the pair played the game until Speed scored the first goal. Shortly after celebrating the goal, Speed told KSI that he had to "toot that ass up" and "put it in doggy style." After a little bit of protesting, KSI assumed the position and Speed whipped him in the butt. But it wasn't long after that Speed had to be on the receiving end, and he was clearly a lot more nervous than his competitor.
This isn't the first time that KSI has done a gaming stream or video where the loser gets whipped. In 2014, back when EA Sports FC was known as FIFA, he shared a video entitled "Slavery FIFA," in which he and ComedyShortsGamer whipped each other. "Going back to my roots," he wrote in the description for the video. So he obviously knows about the connotation of the wager.
KSI also recently went viral after he shared his reaction to Adin Ross comparing the new flavor of Prime—a drink the British YouTuber co-owns with fellow content creator Logan Paul—to "spoiled cum." In a tweet, KSI responded, "Real question is, how does he know what that tastes like lmao?"
