look up any word, like plopping:
 
3.
A word used to shame boyfriends, husbands and sons into picking up their underwear and placing it in the laundry rather than leaving it on the floor. Also used to tease teenagers into hiking up their drawers to avoid showing their man panties to the world. It is generally highly offensive to those who are targeted -- which is really the point.
Please pick up your man panties from the bathroom floor before I run them up the flagpole for all to see.

Please pull up your pants so that we are not all treated to a study of your man panties.
