A covert white supremacist symbol used by Neo-Nazis and members of the Alt-Right. The "fashtag" is identical to the popular hashtag or pound symbol used on social media, but it is used for nefarious purposes to promote white supremacy at Neo-Nazi rallies, and it is used in prisons, by the Aryan Brotherhood, for example. The symbol has only recently been outed as a hate symbol, thanks to Neo-Nazis on the notorious /pol/ section of the 4chan message board.
"John, you can't use the hashtag anymore. Apparently, it's a Neo-Nazi symbol referred to as the "fashtag." Don't you know the real meaning behind it?"
A fashion disaster, fashion victim, fashion faux pas, wearing a regular clothing item in a way that highlights your incompatibility with the selection. Something no person can wear in public without causing alarm to SPCA or PETA. A person who is not able to purchase clothing that fits.
Anything worn by Lady Gaga is a fashtastrophy, anything worn by Cyndi Lauper in 1980's, Don Johnson in Miami Vice, the entire wardrobe of Dallas tv series, Eurotrash. Someone who isnt young or hot trying to get into a nightclub with a small outfit. Anyone who isnt Kylie Minogue wearing her clothing. Anyone who takes fashion advice from Britney spears.
