There were some stories floating around about lighters exploding when used to open a bottle. Using a second bottle can result in the bottle that is being held upside down opening when incorrectly applied which is great fun when it's your buddy wearing it.
I suppose it's mostly a dying art now but there was a time when your average Canadian teenage boy could name 101 ways to open a stubbie; a long gone bottle form as well. It helped to be oblivious to the damage opening the bottle was doing to the items around you. Once seat belts started appearing in cars drinking and driving became a whole lot easier. No more paint
chips off the bumper or bent keys on the chain. Opening with the teeth always seemed dicey to me but I knew guys proud of that skill. A quarter would do in a pinch though it was tough to get much leverage. It seemed to me reaching up and popping the top on the wrought iron railing on the front porch should have impressed the girls more then it did.
Still it is hard to beat the pleasure of opening a bottle with a righteous church key.
