Lawlzerpancopterocaust 

The combination of "Lawl", "Marzipan", "Helicopter" and "Holocaust". Meant to express something so astronomically funny that it can only be described using marzipans, helicopters and the Holocaust.

Jimmy: "What happens when a Jew eats a marzipan?"

Jeffrey: "I don't know, what?"

Jimmy: "He stops screaming for a second"

Jeffrey: "Lawlzerpancopterocaust"
