You notice when the article for an exorbitantly obscure character on Super Mario Wiki gets inexplicably deleted (Why, Kimberlite, whyyyyy?).
You have the promotional Mario toys from Wendy's and Burger King, and you even kept the bags that the food came in because they had Mario pictures and activities on them. You threw away the cups (only years later) because you decided that's nastay.
You name a large portion of your virtual pets after Mario enemies, objects and characters like "Kounbaba," "P Balloon," and "Jugem."

You also imagine down to the last detail what species you would like to be and what you would look like.
You read your Mario Nintendo Adventure Books so much that the covers are disintegrating and no staples or tape can fix it.
You carry a tiny Spiny plush with you whenever you carry a bag. And a little plastic Yoshi on a strap. And a Paper Mario key chain. Bonus points if you're using your Mario purse or messenger bag.
You scour flea markets and thrift stores for cool Mario stuff. You bought an extremely weird looking Raccoon Mario plush for sixty cents and washed it up for your collection.
You decided to buy some Japanese strategy guides and when you receive them you wonder why nobody has scanned the uncirculated art inside them so you do it yourself.
In High School you decorated one of your folders to look like the Dark Prognosticus.

You miss Waluigi's spray paint game from the
Mario Waluigi Tennis official website.
You've bought and won all different sorts of amazing Mario pin buttons but you have no idea where to put them because you don't want to make a hole in your Mario bag.

You wonder if when you drive with one of your windows down, the people can hear your Mario music playing and think you're an ice cream truck.
You're attempting to sew your own Snorkel Snake plush (based off of one that is your fan character).
You take the Super Mario Bros. HQ "Mario Fan Purity Test" every couple of years and you always get the result "Mario is a religion to you."
You feel like you've shamed the whole fandom because you lost your 25th Anniversary Mario CD and booklet (and your mushroom tote... and your Mario Kart 64 boxer shorts).
You actually tried playing Super Mario Homework for fun, and you only liked the surfing parts.
You spent an hour trying to perform the
Black Room of Death glitch in Super Mario 64, on the original console, for your friends.
