Megapode

An exclamation of surprise or shock, usually preceded by "holy."
This is used in reference to the webcomic Lumia's Kingdom, in which a character uses it.

It takes him exactly three hours and forty-seven minutes to detect anything out of the ordinary, to which he will always respond 'Holy Megapode!'
