When one wizzes into a toilet with the seat up and an imperfect seat mechanism causes the seat to fall and break the stream thereby sending piss everywhere.
"Dude did you pee on yourself?" "No dude that crappy commode Pee-guillotined me!"
A pee pee toucher is someone who loves to touch other boys pee pees. They are usually called mark, and love to suck the pee pee as well. Sometimes they kidnap the boys in special pee pee vans and drive them away forever.
