Hass is a what you call your closest friends and an abbreviation for "
horse" despite that fact that no one actually calls their close friends "
horse". Your hasses are your combadres, the ones you call when you brawl or have only a limited amount of meats or beers to share. When a pal walks into a party and yells "HASS!!" and you turn around to a
bear-hug you know you are offically "hasses."
