This is a valuable trick that any frat brother must learn. When a girl wants one of your private fridge beers rather than the warm keg froth that everyone else is drinking, when you give it to her, she'll be very impressed if you can open it with style.

Now, after watching this video, I've tried to do it about three times, and I've only cut myself twice! Chicks totally dig blood right? And scars, at least I know that one is true. 

But seriously, if you can master this one, it's just another handy skill to have in your tool belt. Although if you have an actual tool belt you can probably find something in it to open the beer with.
