Pirating is when you go to your friends house,
pick up a CD or DVD with media on it,
"ARRGGH!" at the top of your lungs.
make sure to sound very piratelike when doing this to make sure you Pirated the CD/DVD correctly.
Joe: I love Pirating music,
Steve: I Pirated a CD a minute ago
Joe: Did you scream "ARRGGH!" loud enough?
Steve: yep :P
