Use of speaker phone to ambush/embarrass someone on the other end of the line, who is unaware that the speaker feature is in use.
So, Christie was just on the phone with her boyfriend and was singing in this hideous voice, only to realize he had her on speaker phone and his buddy heard it all.....That, my friend, is what I like to call "speaker pwned."
