Explained: The Top 5 Internet Slang Terms Everyone's Using In 2025

The ever-evolving landscape of internet communication continues to introduce new slang, frequently driven by Gen Z and disseminated across platforms like TikTok and Twitch. Understanding these terms is essential for navigating online interactions effectively in 2025. Here are five prevalent internet slang terms currently in widespread use:

Rizz: This term is a shortened form of "charisma" and refers to an individual's skill in flirting, charming, or attracting others, particularly in a romantic context. Its popularity surged from online gaming and social media culture, becoming a common descriptor for someone's ability to effortlessly engage with others.

Delulu: An informal abbreviation of "delusional," "delulu" is often used humorously to describe someone who holds unrealistic or irrational beliefs, particularly in relation to their aspirations or fantasies. While originating in fandom communities, it has broadened its application to mockingly or affectionately refer to overly optimistic thinking.

NPC: Derived from the gaming term "Non-Playable Character," an "NPC" in internet slang denotes an individual who appears to lack originality, independent thought, or emotional depth. It is frequently employed to satirise or criticise those perceived as acting generically or following trends without genuine awareness.

Slay: This versatile term signifies doing something exceptionally well, looking outstanding, or achieving a remarkable success. "Slay" is a widely used word of affirmation and praise, applicable to various situations from fashion choices to impressive performances. Its use expresses strong approval and admiration.

Ate (and left no crumbs): Building upon "slay," this phrase emphasises a complete and utterly dominant performance or achievement. When someone "ate (and left no crumbs)," it means they executed a task or performance flawlessly, leaving no room for improvement or competition. This hyperbolic expression conveys absolute triumph.
