When people find out about something kinda old and then flip out as if it's way new. Bonus points if they try to explain what it is, even after you tell them it isn't new and that you know what it is.
A perfect example would be the time my friends discovered Minecraft.
Friend: "Hey man, did you hear about that new game 'Minecraft'?"
Me: "Yeah, it's not really new and I-"
Friend: "Yeah, well, it's so cool. You build and blahabalabahalab"
