An English teacher that you just hate. The Mrs Nelson's of the world are usually old and have that amazing ability to give you a death stare that makes you want to go crawl underneath your desk and wait for the next nuclear bomb. They are sometimes but not always lesbian though they do show lesbian traits. If you know a Mrs Nelson I am sorry I really am.
Friend 1: Omg that person is giving me a death stare i think i might just go die now
Friend 2: she must be a Mrs Nelson
Friend 1: Agreed
