The act of checking your mobile/cell phone for a non-existent call or message whilst on vibrate alert.
I was totally waiting for a call from a hot chick but all I got was ghost vibrations. Bummer!
When you feel your phone vibrate in your pocket (whether it really is or not) and you go to check your phone and -guess what? No fucking calls, no fucking texts, just your same shitty phone playing tricks on you.
The other day i felt my phone go off, but then I remembered I left my phone at home. Damn ghost vibrations.
