a pretty cool person who loves theater and its a lifestyle. they make lots of musical references even if you don't understand and constantly burst into song. it's contagious and soon you as well will burst into song. if its a female then they generally are super sweet and for the male species not only are they likely gay but honestly kinda hot... a theater rat can also have a cute nickname as "pip-squeak" and if they like cheese to be sure to bring it up at least once.
