The act of checking your mobile/cell phone for a non-existent call or message whilst on vibrate alert.

A casual invitation / threat used by an individual that is not afraid of fucking someone up.

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.

when keeping your phone on vibrate, you experience the sensation of vibrations in your pants pocket, purse, etc. only to see that nothing has taken place on your mobile.
