Hayliesm
A rare disease caught by someone when their friend is annoying, useless, dumb, emo, not funny, sarcastic, gay, can't read, can't count, can barely remember their left and rights and generally is pretty useless but you still remain friends with them for some unknown reason even though they text you in three-four letter words consisting of 'kys' and 'die' and 'stop' and on rare occasion when they know any other words, 'loser' even though they most likely spelt that wrong because they are stupid.
Don't come near me, I've got Hayliesm. It might kill me.
