Some drinks served at Tiki bars include co-opting previous cocktails with exotic sounding names or foreign backstories, such as the "Bloody Nelson", Blow My Skull, Boomerang, Corpse Reviver, Diki-Diki, Doctor Funk, Planter's Punch, and Singapore Sling. New inventions by Beach, Bergeron, and others included the Coffee Grog, Navy Grog, Lapu Lapu, Outrigger, Pago Pago, Rum Barrel, Shrunken Head, and Tropical Itch. While many were created expressly as "tiki drinks" (although such a term was not used at the time), others were simply new World War II era cocktails made overseas that could quickly be assimilated into the formula, such as the case with the Suffering Bastard.
