You all know that feeling.  You are hanging out with your friends at the mall and they point it out.  Not discreetly and not quietly but in the middle of the crowded cafeteria. 
“Your fly is open” She bursts out “nice underwear”.
Your face goes red, a couple people stare and a group of hot guys’ chuckle.  You high tail it to the bathroom because nothing is creepier than someone grabbing their crotch in public.  That dreaded zipper, never going up when you need it to and never going down when you have to pee very, very badly.  It is almost like it has a mind of its own; a trickster that shows no mercy.  So next time you use a change room or a bathroom be cautious to not become the next victim of the lord of the flies.
