Big Man Syndrome (BMS) is marked by delusions that because there's a girl willing to sleep with you and hang on your every word (hence being a "big man") that everyone else, particularly males, are equally enthusiastic supporters of the mindless bullshit you purport. Other symptoms include: unwillingness to listen or compromise, unreasonable demands you expect to be fulfilled and the belief everyone else shares your interests.
