For fudge cake
A more polite but equally comprehensible version of "For fuck's sake". They'll know what you restrained yourself from saying. Can be used in both senses of the original phrase.
Example:
1. "Isn't that your girlfriend with Texas Pete over there Superted?"
"For fudge cake! I just bought the heifer a holiday!"
2. "For fudge cake, please refrain from sticking your fingers in the fudge cake."
