You win the interwebz today! I thought the same thing.  You know, fellow shitlord/ladies, this is why we got that gunt punt training in the first place, to handle situations like these. One good gunt punt, and you'll never have to deal with a fat fuck taking up the stairs again as word will spread about "that mysterious person who kicked Cindy down the stairs, and she was only as big as Cindy's this chin!". People will see your size and think you're magical or something.
