TBD's 

Acronym, standing for Titties by Default. Refers to the massive protrusions of fatty tissue present in the chest area of overweight women, and occasionaly men. Not to be confused with BAT's (bomb-ass titties), Titties by Default are not composed of breast tissue, but rather an inevitable dispersion of fat cells throughout the bodies of those afflicted. While TBD's are responsible for giving fat women a false sense of confidence and self worth, they are equally capable of deceiving unsuspecting onlookers, and masquerading as BAT's.

Stel: "Holy shit, that girl eating the nacho plate to herself has PHENOMENAL breasts. I can't stop staring"

Me "No dude, they're TBD's. If I was 3 bills I would have phenomenal breasts too."

TBDS

Turtle Boy Derangement Syndrome. TBDS is an unofficially labelled psychosis that people who cannot stand Aiden "TurtleBoy" Kearney, the Massachusetts journalist who exposed the police corruption in the Karen Read trial. It normally shows itself on Twitter/X. Often times it happens to people who originally were on TurtleBoy's side, but have switched sides at some point from Free Karen Read to the Anti-Free Karen Read movement. People afflicted with TBDS agree with the Commonwealth's prosecution of a citizen-journalist who is looking at a combined punishment of over 100 years in prison for doing journalism and asking questions in the guise of "Witness Intimidation." It is named after Trump Derangement Syndrome, or TDS.

The House Defendants in the Karen Read trial, as well as Kate Peter, Mike from The Yung Jerks on YouTube, and Brian of LTL Media on YouTube have full blown TBDS.
