look up any word, like dirty sanchez:
 
1.
n. (sü-p&r dæd)
A man who shouts profanities at little league baseball games and threatens peewee coaches. Super dads are often seen standing the court-ordered distance from a school yard watching little girls play in the sand through binoculars.

Can be compared to world's greatest grandpa
Coach (after having heard enough of drunken man's foul language): Alright super dad, get out of here before I call your parole officer.
