I'm not usually a supporter of apps that don't have much of a purpose, especially the ones that fall under the "pranks" category. Now, I say "usually" because most of the time these apps are pretty stupid (I'm looking at you, iFarts) or not very prank-worthy.
Rarely, however, worthy apps do come out, and the recent Shavester is one of them - it caught my attention due to the freakout potential of turning your merry friends into something like Britney here, except not as happy, if only for just a few seconds.
The premise behind Shavester is very simple:
Step 1: Install the app and start it.
Step 2: Find a friend with hair. Bonus points: find a friend with hair with a known hair obsession (aka a girl).
Step 3: Press and hold the button which will turn on the buzzer and make the phone vibrate at the same time, creating a pretty good illusion of a real hair trimmer.
Step 4: Slide it on your friend's head and creatively comment on what you're doing. For example, "I just pulled a Britney on you" or "Oops, I did not mean to do that."
Bonus: Do it to your boss and see if he gives you a raise for trying to boost the office morale.
