To put on a user flair on a subreddit, an integral part of r/politicalcompassmemes' culture.

Generally, user flairs are used to categorise the users on a subreddit, like the personality typology subreddits, the alignment chart subreddits, political subreddits, any reason to categorise people. Or, you could make the flairs editable, as an extension of one's username on the subreddit.

Obtaining a flair is what to 'flair up' means.
Unflaired: Hello, I'm new to this subreddit.
