flac 

n. An audio compression algorithm which is sonically superior to the more widely-known .mp3 compression algorithm, due to the lossless nature of .flac compression. Audio encoded in .mp3 are, however, typically 1/10th the size of .flac, which may be one reason why the .mp3 format retains such popularity over the .flac format.

I encoded the entire Led Zeppelin catalog to .flac, so I will be able to enjoy the best songs ever written in crystal, clear lossless audio even if my daughter scratches up all my original CDs.

FLAC 

Fucking Loser Ass Clown

⸻

Definition (Core):
A two-faced jerk who pretends to care but is really just trying to control you, mess with your head, or make you look crazy. FLACs act like they know everything, but deep down they’re just insecure manipulators who can’t stand being exposed.
Traits of a FLAC:
• Gaslights you while smiling to your face
• Acts “worried” just to shut you down
• Trashes your reputation while playing the victim
• Shows up late to the situation and still thinks they’re the expert
• Demands respect while contributing nothing

Usage:

“That dude said he was checking in on me, but he twisted everything I said to make me look like the lunatic.”
“Don’t waste time arguing with a FLAC — facts bounce right off.”

⸻

Bonus Quote:

“Loses new friends faster than a free sample tray at a stoner festival.”
