I believe I've solved profanity.
At least, I've discovered a formula for inventing nonce-fuckyous that keeps me entertained while yelling at New jersey drivers, and prevents my repertoire from getting stale.
First, choose any one-syllable profanity. The short ones tend to be punchiest and most visceral anyway.
Then take any mundane single-word trochee--a two-syllable word with a stressed first syllable and unstressed second syllable--whose first syllable shares a vowel sound with the profanity.
Et voila! You have a metrically ideal nonsense phrase that people will involuntarily try to picture, disgusting them, delighting you (assuming you're as big a child as I am), and getting you thrown out of restaurants.
"Goddamn asshole!" may have long since lost its punch, but I guarantee "son of a cunt smuggler!" will have, if nothing else, the shine of novelty.
The system hasn't failed me yet.
