It is the name of a subreddit in which one posts images of people not getting a joke. The "woooosh" means the sound of the joke that goes over one's head.

The term has been twisted ever since the shitty Reddit channels rose, and nowadays, r/woooosh is mostly said by 12 year old children who think that Reddit is cool. In 99% of all known cases, they are funnily enough the ones who missed the joke. Correct a spelling mistake? r/woooosh. The joke is unfunny or overdone? r/woooosh. Asked an earnest question? r/woooosh.

Luckily, more and more are getting sick of this shit, so r/woooosh is facing stigmatisation. I pray that one day, we will live in a world without r/woooosh.
Person a: Nobody: YouTube recommendations:

This is the right spelling, talking to you r/whoosh-ers and r/woosh-ers, the sound of a joke flying over your head, made into a subreddit for people to make fun of people who don’t get jokes.
OP: I hate people who beg for likes, like if you agree
TP (Terrible Person): But you just begged for likes!
OP: r/whoosh
AP (Another Person): You spelt it wrong, it’s r/woooosh

This subreddit has probably been linked outside of reddit more than even inside reddit. It means someone who didn't get the joke and took it seriously.

If you encounter someone in Youtube or any other social media who didn't get the joke, just say 'That's the joke' instead.
Reddit comments:

Person 1: *says a joke*

Person 2: *takes the joke seriously

Person 3: r/woooosh
