a shit test is usually when a woman gives a guy a hard time specifically to see how he reacts. they will do this so they can see the type of guy you are and do find out if you have certain undesirable traits such as neediness and clingyness. one of my favorite shit tests is actually from the movie hitch. during the bar scene a guy chip comes up and starts talking to her and is lost for words when she gives him the shit test about his name. after that all is lost because he wasnt able to come back from it and ultimately gets put right into the category "AFC"
