a phrase made up by Ian Soliterman, a Canadian kid. usage of this word applies to any question, even if it isn't a yes or no question, it could even be a math question! You can even use it on a guy. it works great on teachers(especially male), parents (mom AND dad), and anyone else that tells you to do stuff. also a great way to start conversations with your friends on msn and aim. and is the coolest user on nexopia - yesmam
Teacher: Did you finish your homework, bobby?

Teacher: I'm not a "ma'am" i'm a male
Bobby: Yes MAM
