A woman that 90% of the time talks about how she loves stuff that is so fuckin boring you consider hanging yourself.

Hint, When being spoken to by your mother in law, listen and dont lie, THEY KNOW EVERYTHING.

A son's mother - who after he takes a wife, becomes jealous of the wife and considers her competition for the son's affection (which is gross and somewhat incestuous). If not put in her place (told to fuck off) by the daughter-in-law immediately after marrying her son, the mother-in-law will grow fiercely competitive and attempt to wreck the son's marriage by whatever means necessary.
My mother-in-law is jealous of the fact that I married her baby boy and helped him to become a man. What a sick bitch.

Mother of spouse. Self rightous, beastly, female entity. Master of deception. Often dyes her hair in order to reflect a younger age. One who professes to be all knowing. She Who is Evil. The Heartless One.
After his mother in law's week-long visit, Rob had to call an excorcist and bathe himself in Holy Water to rid his home of the evil presence that she left behind.
