Oh boy. Here we go into a giant rabbit hole filled with either positive definitions or hate definitions. And both ways do NOT have the likes topping dislikes...
Generally, a Slipknot fan is...well...a fan of Slipknot. That's really all there is to say.
Slipknot also has a general name for these fans: "maggots."
Some "common" (real maggots may correct me because I personally don't care about Slipknot) characteristics include:
1). Slipknot merch
2). huge factual knowledge about Slipknot and all side projects and other related artists
3). homemade masks that legitimately look like a Slipknot member would wear one (depends on if they're a hardcore fan or not)
4.) getting hated on which I DON'T condone, don't go out attacking anyone for their taste in music, especially if it's a genre/band you don't like at all
Josh: Okay, I'm just gonna search "slipknot fan" on UD, let's see what I get.

Josh: What the fuck?
When a person (mostly homosexual) makes a slipknot out of cat shit, and let’s it ferment and dry until it’s rock solid. The aroma of the fermented cat shit kills you before the slipknot dose. And I’m most cases everyone around.
Damn Nigga he really made a liams slipknot and killed 4 people in the process.
When it's that time of the week and another Sunday rolls around on another leg day. You put on your best outfit, get your best slipknot playlist together, and you go torture some fucking legs at the gym while pretending you're moshing at a Slipknot concert.
Ayo, where TF are you ?!?! It's fucking Slipknot Sunday and I'm currently at the gym, headbanging and moshing alone. Get your shit together, or you'll be removed from the Slipknot Sunday club.
