Derived from munt
(to vomit), a power munt is any regurgitation that is of such awe inspiring force that it requires the adjective "power" placed in front of it to convey the immense volume of the munterial and the violent manner in which it was dispelled from the body through a combination of the mouth, nose and, in extreme cases, the eyes. Something to be proud of the morning after.
