Get the RedTagged mug.
The label one may place on a newcomer who

a. Introvert Redtag ( you don't know they are mentally unstable untill it is too late) "simmering Redtag"

B. extrovert Redtag (they are fucking crazy and you know it the second they walk in the room) "flamming redtag"
That dude Manny thinks everyone is out to get him because he has a Jerry curl, colored contacts, and a fucking pinky ring! Redtag!

People can be converted to Redtag by their social surroundings and/or genetics
