An alcoholic beverage with an Irish whiskey base that, when lit, will have a blue flame to it. Produces a nice blaze, and is more enjoyable in a dimly lit room, where the flame can be appreciated.

Place a lighter outside of your clothes(underwear, pants panty's, shorts, so on...)put against your anus. Blast a large explosive flatulence (fart). While blasting one, light the lighter for a Blue Blazer flame.
A gaseous combustion released by the anus once lit with a flame causes a Blue Flame.
