Insufferable

It's very rare that I have to block someone on Facebook but this one person was just so insufferable I wouldn't gain anything from being Facebook friends with such an imbecile

They would post really passive aggressive things on my content. Stuff like "get gud retard", "this sucks", something related with genitals, or just a random "Fuck you" completely out of context. Why do people do this, there is nothing accomplished from doing this. They are trying way too hard to be funny but they just turn out to be obnoxious
