An acronym for "Wrong Person". When someone says
something to another person, but at the
time, did not notice that they were talking to someone else, who they didn't
mean to speak to. Often used in instant messengers.
"An example situation in an instant messaging room:"
SomeGuy: Hey, remember when I laughed at that guy with the
giant tumor on his
head?
SomeChick:
Umm, what?!
SomeGuy: Sorry, WP.
