So your friends are on your last nerve. Your girlfriend is really lame and you just cant find a way to well, blow her up. You can not blow her up in reality to many legal issues but with iC4Prank you can blow her up in ten seconds.
Here you are at a nice restaurant with your girlfriend. You get up to go to the bathroom without forgetting to set your iC4Prank to go off. Leave your iphone somewhere and get out of there before six seconds are up. At four seconds your unsuspecting girlfriend will hear "A lil C4 four knockin on your door." then during her confusion, BOOM!
Enjoy this prank and remember to set volume to full!
