Originated from 4chan. Basically a SJW that jumps into 4chan threads to try and make anon feel bad for being on 4chan. Thread hilariously erupts as anon calls out the discord tranny and tells them to BTFO!!

OP: Wow anon, looks like we are finally winning the war against the evil alt-right incels.
Anon: /pol/ isn't for discord trannies, get the fuck out.
OP: *GASP* ...h...how dare you... y...you call me out.... TRIGGERED
Tannies is a word used to refer to the seven members of the legendary boy band BTS or Bangtan Sonyeondan. This term belongs to them and them only, anyone else using this term to refer to some other entity is invalid. Don't even try. Also, keep in mind the 's', because Tannie is often used to refer to Kim Taehyung's pomeranian and best boy Yeontan.
