a friendship terminating action. a premeditated plan of something awful towards another close to you, with evil intention. a practical joke gone too far.
after being made fun of for being a dog lover, i thought sneaking my best friends dead dog into his bed would teach him a lesson, but my decieviouse actions led my best friend to suicide.
