Aunt Sally
Something or someone set up as the object of criticism, derision, or as an easily defeated opposing opinion (i.e., a straw man). Named after a game where sticks or balls are thrown at a clay or wooden head (the Aunt Sally). Primarily heard in UK. I hate hanging out with that crowd, they always aim their jokes at me like I'm an Aunt Sally. My opponent's representation of me is nothing but an Aunt Sally; he refuses to debate me on my true position and instead attacks a fictitious one from afar!
Aunt Flo
euphemism A humorous term for a menstrual period. A pun on the "flow" of blood and tissue from the uterus. Ugh, I have horrible cramps because Aunt Flo has come to town.
