Get To Know The Meaning Of These Popular 2021 Internet Slang Words


Definition: Sus became the go-to internet slang term in recent months, thanks to the popularity of mobile game Among Us. Short for “suspicious” or “suspect”, it’s often used to flag a situation or a person, hinting that they’re not trustworthy and some sort of drama will follow suit. 

Example: “That person is sus. I don’t trust a single word he says.”



Definition: This internet slang term first took shape as a dance move that went viral on Vine in 2014. It was loosely used as a verb to describe said dance move, which involves slightly bending the knees while swiftly moving your arms from left to right, sort of like a “dab”. 

Since then, the term has evolved to become an exclamation, although it still can be used as a verb for discarding something at high velocity. 

Example: “I got a promotion today, ya yeet!” or “He grabbed her smartphone and yeeted it into the bin.”

No Cap

Example: “He just bought a pair of sneakers for five thousand bucks. No cap.”


Definition: No, it’s not to take a swing at someone. This internet slang expression is used to express just how good something is.

Example: “Don’t sleep on this new chocolate bar. It’s so good!” or “Don’t sleep on Dua Lipa’s new album. It’s pretty good!”
