Get the FYBmug. Fuck You Bitch”** — a slang term popularized by Toronto artist Lil Stee in his breakout song FYB.
Used to express anger, pain, or disrespect toward a girl who did you dirty, cheated, switched up, or played with your heart.
Now growing in Toronto culture as a way to say you’re done with the drama and not looking back.

Get the FYBmug. FYB stands for Fuck Your Bitch or Formal Young Billionaires Clan. This clan is known to be one of the best performing gaming clans of the 21st century. Most people fear the power that this gaming clan wields. The leader of this clan, Yahir, is said to be the best dick sucker in the community and will do it for free even. FYB mainly games on Call of Duty BO4, Fortnite, and iMessage games. This clan has even made enough money to buy a 400 emblem, so suck it noobs cause FYB is the best clan. And you better watch out or we will FUCK YOUR BITCH!
