A type of video format that stands for Web Media. It’s extremely similar to the MP4 format, the main difference between them is the video codecs they use. (WEBM uses VP8/VP9 and MP4 uses H.264)

No, not all WEBMs are memes. The association with WEBMs and memes came from YouTube compilations of memes that they got from 4chan (which only lets you use WEBM as a video format, the only other file types allowed other than WEBM are GIF, PNG, and IMG) or from someone sharing a meme to them that happened to be in WEBM format.

Just because a meme is in WEBM format doesn’t automatically make it good. And just because a meme is in MP4, MOV, GIF, etc. format doesn’t automatically make it bad.
I downloaded this WEBM from Wikipedia, it was 10 minutes long and it was footage of a documentary

WebM is a Video-File Format optimized for Web Browsers, but since 2018 stupid clueless retarded people are associating it with meme's.
Casual Tech Person: "I'm exporting the video to a WebM container."
Retarded Person: "But that video isn't a meme.."
Casual Tech Person: "Are you fucking retarded?"
