An overused youtube comment in which a poster that has viewed a video produced by a popular youtuber that has just been uploaded. If a lot of people watch a video that has just been released at the same time, the youtube view counter gets stuck at around 300-320. Also called the "Under 306 Club" "Under 311 Club" etc.
Thumbs up if you are in the under 300 club.

Welcome to the Under 300 Club. Have a coctail.
