a nickname for someone who is super cute, and a really good friend, and slightly odd, but the best person ever! the reason the nicknames furball is because they are cute and warm and fuzzy like a kitty, and just a lil bit not normal

A tightly packed mass of hair regurgitated by a cat or other feline, or a dog, or an other hairy mammal, that comes from it licking itself all day long because it likes to do it, preferably while people are watching. In humans this behaviour has a scientific name, but it still does not make it any less disgusting.
A middle aged balding man with astigmatism and a sinister squint walks into a doctor’s surgery one day and says to the receptionist, “Well Doc. I puked up this massive hairball from my stomach this morning, straight after breakfast, I guess that this means you think I should stop eating my hair them?” Needless to say the receptionist was none too pleased at hearing this news about a man producing a furball for breakfast, not least because she had just came back from lunch.
