1. Meaning & Definition
CTFU stands for “Cracking The F* Up”**—a slang term used to indicate that something is extremely funny. It’s similar to saying “LOL” or “ROFL,” but it usually implies a stronger, more intense reaction to humor.
- Primary meaning: Laughing uncontrollably at a joke, meme, or funny incident.
