A “Happiness hog” is a person (usually a lesbian teenage girl) who is constantly bragging about their depression.
They can’t say “I cut myself” for 0.1 second.
Dude: *edgy suicide joke*
Girl: “I wanna commit suicide I cut myself and broke up with my girlfriend I have no friends at school and my mom abuses me waaaaa I’m a baby”
Dude: Wow such a fucking Happiness Hog.
A fat, greasy, unbathed, soaking in the smouldering heat nasty individual that cant even walk on their own 2 feet they haven't seen in years so they utilize scooters the Walmart.
Dear God, look at that chuna hogcreeping the aisles harvesting all the apple fritters and crate of donuts!
People thought the compliment hog in class needed to get high on either cocaine or ecstasy more than she needed a compliment, since she seemed like someone with a low dopamine level in her brain.
