i was laughing through this whole thread
and yes its happened to me and it sucks. heres what i do: i start to push it out, realize its too big for my butthole, so i let it hang there for a while as the pain goes away. when i get the courage back up i push a little more out. repeat last sentence until its all out.
the worst thing about these is that you cant cortesy flush, its has to go down all at once.
