lol
when you MADE the game and still play it
when you see a spider, pull out a broom and say "suck my pulse rifle" and try to shoot it.
when you play LAN alone
when you play wow and this in side by side panels
when you bought a top of the line dell XPS to play trem
when someone talks about earthquakes, you tell them to stop complaining or get off the thermal map
you tell your mom to stop camping so you can get by
you still live with your mom, and your 40, and whenever shes gone you check the door for lisks
you live in your own basement, and have a fully functional luci
you locked the mailman in the closet thinking he was an adv granger trying to spawn an egg in your mailbox
you have trem on a laptop
you talk in chat (teamspeak, whisper, all etc.)
