1. You have to cut of your penis. If you dont have one your half way there.
2. Have a Twitter account with an anime pfp preferably have a name that is either sarcastic or smug ( bonus points for nonsensical emotes)

Troon yourself out, get an underaged-looking catgirl model so you can be a vtuber, play only LoL, WoW, or Osu, obsess over the pink-light blue-white aesthetic, threaten to self-harm or kill yourself once a few months, and tease your nudes twice a year.
