strescuo

Signal given to close friend or family member for help, when one is cornered by an unwanted conversation or undesirable person.


Example: As her boss's son began to explain the details of how his collection of beetles was organized, Susan realized that she was trapped, unable to walk away politely. In desperation, she sent out a strescuo, hoping that her co-worker would notice the gesture and provide a pretext for Susan to leave.
