A Butt Father is a man who in a relationship, short or long, is the one who penetrates the other's posterior at all times.

It does not matter if the other is male or female, you can still be butt fathered.

One who is the one who gets Butt Fathered is called either a Butt Son or a Butt Daughter.

A woman who uses a strapped-on dildo to penetrate anally is called a Butt Mother.

Plural is Butt Fathers.

It is unknown why they aren't called Butt Husbands or Butt Wifes, it is a strange conundrum...

Get the Butt Father mug.
A priest, oftentimes Catholic, who has repeatedly inserted his penis into an altar boy's asshole. He has been accused multiple times, and moved to other churches in order for the Catholics to maintain their holier-than-thou attitude.

Father Butt Dart is a pedophile, not to be confused with a homosexual. The upper age limit is about 12.
Did you hear what Cardinal Law said about Father Butt Dart when he was finally called out in public? He said God only chooses special young people to have "that kind of a relationship with a priest".... The higher-ups sure do protect Father Butt Dart.
