A fictional shot or drink often requested in cocktail/shots bars for one of two reasons, either:

in order to initiate conversation with an attractive barmaid

or

to cause general confusion as the bar staff search the shelves and the manager is consulted.

In one bar in Swansea the request of 6 Cherry Bombastics marks the arrival of a notorious group known to the staff to be fond of general mischeif and tomfoolery.
Bar Staff: "Next?"
Johnny Inches : "6 Desperados and 6 Cherry Bombastics Bombastics Please"
Bar Staff: "Oh not you lot again"
