I live for kniferzzz. What i use for a hooter is i took a redrum bottle and cut it, it's glass so i put it in the freezer, gives nice smooth hits. Roll your bud into little b b's, it don't take much. Works hella good with 2 or more people driving for one another. Oh and if you don't know what redrum is it's a lickher, good shit man, drink of tha killaz.
