Somebody who can't tollerate somebody else for their appearance their habits or anything arcane about them. The polar opposite of a hater is a Juggalo. Any Juggalo feels more love than they could even thought they have ever felt. Take it from me it feels good to be a Juggalo.
hater: fuck that juggalo he smokes crack and does drugs and is a huge hater
haters friend: hes auctually a pretty cool guy and doesn't judge people when he first sees them you're the hater
