Slang

What does "to blow up" mean in internet slang?

The structure is a phrasal verb borrowed from its real world meaning of exploding, repurposed to describe sudden and massive popularity. It is used to describe content, creators, or trends that gain an enormous amount of attention in a very short time, such as a video getting millions of views overnight or a meme spreading across every platform. People typically say "this blew up" when their post far exceeds their usual engagement.

Examples
