a steam boat willie is when you find a homeless man and call him willie, place a captains hat on his head then he proceeds to shit a horrible homeless shit on your chest. while he does this you yell out loud "I I caption!"
hey girl I'm so in love with you. lets get crazy and do a steam boat willie together!
