Grammatical Rule of Thumb 

1.Using "he" in a sentence as the default pronoun(instead of "he or she") for someone of an unknown gender,a person using this rule is thus considered a sexist by feminists.
2. Rule that compares such a person previously described to that of a wife-beater(wife beating is where the Rule of Thumb part originates).

My feminist English teacher yelled at me about my use of the Grammatical Rule of Thumb in my English paper.

grammaries 

1. The breasts of an elderly woman.

2. Saggy, flat breasts that have a slight odor of sour milk or mildew.

3. Aged pancakes.

My grandmother Helga always made sure to roll up her grammaries and secure them with rubber bands to prevent the uncomfortable pinching that would occur if they slipped below her pant line.

When he returned home, John ate the leftover grammaries that had been sitting on the counter since last Tuesday.
