A mixture of juice (pineapple, fruit punch or orange from concentrate) and alcohol usually rum (White or Aged) that taste nothing like liquor and fools many into believing they are drinking only juice until the effects start to take effect. Happy juice is usually stronger than drinking the same liquor on another basis as many bottles can be used and the taste barely changes.

Recipe can be experimented with and varied to drinkers preference
Some girls don't like to drink straight hard liquor so they drink Happy Juice as an alternative and get even more fucked up.
