Terminator Cell Phone Stun Gun
"I'll be ba-ZZZZZZT!" There's your Terminator. "New phone, who diZZZZZZT!" There's your cell phone. ZZZZZZT! them together and what do you get? The Terminator Cell Phone Stun Gun.
Terminator calls their self defense tool "the most realistic cell phone stun gun on the market today," which makes it great for prepping to fend off a potential attacker without drawing attention to the fact you're drawing a taser. But also makes it not so great for getting confused with your actual iPhone and giving yourself a buzz instead of your mama when you go to call her.
Best to keep the Terminator Cell Phone Stun Gun far from the curious eyes and wandering fingers of your kiddos, and drunk friends Cornelius, too.
On second thought, if Cornelius really wants it, might as well let him have ZZZZZZT!
