Using your mouth and lips to create popping sounds to recreate morse code. This can be used when communicating with friends and coworkers in a new way so no one will know exactly what it is you are talking to each other about.
A bank teller used MCMP (morse code mouth popping) to alert a coworker she was being robbed to alert the authorities without the suspect in question even knowing!
