Redhats are neither whitehat nor blackhat, but a mix of both. Adapted from early RPG games where white mages used healing, protective "good" spells, black mages used elemental, destructive "bad" spells, and red mages had a selection of spells from both.

Examples of redhats:
- People who are hired to find security holes in a network, do so, but create new exploits in order to take advantage of later.

- Someone who breaks into a secure area and then informs the owner that they can fix the security holes if they hire them.

- Someone who works in network security and uses their job experience to take advantage of exploits either within their own company or elsewhere.
This redhat is offering to fix our security holes for $5,000.

Get a redhat mug for your buddy José.
A fervent supporter of Donald Trump. Redhats typically reject all reputable news sources as "lame stream media" and only believe what they hear from chain emails, Trump himself, and fake news articles on Facebook.

Typically incoherent and bigoted, redhats believe they can win any argument by repeatedly shouting "snowflake" and contesting basic facts.

Named after the infamous "Make America Great Again" headwear, on the pattern of brownshirt.
Don't make racist jokes, Dad, you sound like a goddamn redhat.
