Hateslop

A person (usually a child) who feels the need to hate anything and everything on the internet that they don't find appealing, in order to put others down to cope with their own bland miserable lives, usually because someone else told them to hate said opinion.

Person 1: I hate ____, ____ is awful and corny and I hate everyone who enjoys it.
Person 2: hey, thats not very nice... :'(
Person 3: Just ignore it, Person 2, it's just hateslop.
