Get really drunk. This piercing is best done under the influence of Tequila because of its rather inherent violent and bad-ass nature. You can also use Jack Daniels or Anti-freeze. Dont mix them though.
Punks dont drink mixed drinks.
Steal something long and sharp. Skewers are good, as are those pointy things that you put kabob on. Some people like to use hatpins. Just dump some left over jack daniels or something on it and wipe it clean on your tongue. Punks never waste alchohol.
