Get yourself a highball glass. A shot of the herbal liqueur, Jagermeister specifically, goes in first. Pour a can of pineapple juice, usually 5 to 7 ounces, on top. Then either toss in a shot of grain alcohol, high proof vodka, or rum or layer it carefully on top. If you do the latter, set it aflame and deal it as a shot (this is an Afterburning Chuck Jager with Reheat, courtesy of my good drinking buddy Karma). Doing it "with Reheat" may be easier if you use a pineapple liqueur or pineapple juice from concentrate (mmmm, slushy).
