A kid who pops his pimples in the bathroom shooting the gooey contents of his infected pimple on the mirror and doesn't wipe it off. Likes leaving a nice splatter of pus, blood and dried sebum for everyone to see as a form of passive aggressive psychological warfare.
Kevin eats the bloody contents of his pimples and likes to leave popped pimple splatter on walls and mirrors. He's a faggot too.
