Honestly I wouldn't be surprised if that wasn't an accident at all, and that's just how he talks now, substituting that word whenever possible.At 2:36 he actually botches it up and says "everypony" instead of everybody. Time to expect even more broken english out of chris in the future!
Also I thought someone told him to do this but as expected he just turned it about himself at the end.
at this point, it's not even a question it's a factI'm wondering if he accidentally drops "everypony" irl for no reason
