An incredibly edgy way of saying “ fuck off ” except it’s made by 12 yr old cyberbullies who think they’re edgy for not coming to supper at their family dining room.

Sometimes it is also written by a neckbeard who lives in his mom’s basement and wears fedoras all day like the incel he is.
Mike: I dislike like (insert bad piece of media here) because of (insert good and valid criticism here)

Timmy: KYS you piece of shit go drink bleach

Mike: I don’t believe that what you just said to me was either nice nor even a counter argument

Timmy: Fuck off and suck my dick I’m totally not gay btw haha
