A bit late to the SlapChop party but the guy discovering it for the first time is a 23 or 24 year old Brit according to his twitter profile, whereas the guy calling himself "fucking old" is only 30 anyway. 73% of this forum is 25 or under, so maybe it's not to do with age, and more to do with whether you spent your teen years indoors watching SlapChop memes?
