Dad-gummit

[Michiko]

Dad [gummit] is a very [simple thing] to explain.
First, you use reverse [dyslexia] for the first two letters in each term.
Gud dammit.
Then one simply fixes the first term by changing one vowel.
God dammit.
And there you have it.

[dagnamit], Humorous, less [profane] variation on [damnit].
