What’s small, personal, carried in a single woman’s luggage, and vibrates if the switch is jiggled?

So, we are taking grandma to the airport and having a laugh at her expense about various things that have happened over the last few weeks, including the Lebanese cucumber.  Which she will never live down, I am sure. And R grabs her bag and hoists it out of the car, and once inside, places it on the table ready to be x-rayed and taken though the scanner on the conveyor belt.

And her bag starts to vibrate. And emit a buzzing sound. And R raises his eyebrows and simply says “I do NOT want to know – it’s those lesbian things again” and walks away. And I dissolve into giggles and simply crack up and one very red faced grandma unzips her bag to prove to all who are watching that it is, indeed her leg shaver that is buzzing, and not anything suspicious or cucumber like.
