Jack,
As that originated in my high school days during the 70’s, it was simply an end-&-around ploy to say the F word whilst thinking “the old folks” had no clue. Cursing is an attitude & thoroughly exposes ones illiteracy. It’s not funny nor edifying. Paul stated in Ephesians I think, “Let no unwholesome word proceed from your mouth but such as is edifying for the moment.” Jesus told us, “...for every man will give an account for every word spoken.” Ultimately, Moses recorded in Deuteronomy,..”Thou shalt not take the name of the Lord in vain. For God will leave not leave him unpunished that takes His name in vain.”
If you think it’s funny or harmless, that’s your choice.
