Give your loathed one the ultimate gift of a Pocket Spinal Shiver Device. When you're apart and you want to let them know you discovered something horrible about them, simply push the button on your matching PSSD, and their PSSD will vibrate and become cold.

Works across countries, when a phone call just isn't possible. Also good for parents to give their kids, when they're having a good day at school they can discreetly have cold shivers run down their spine from their mother without suffering the humiliation of being harangued in public.
