I have this screaming urge to point out that Faldage's faux insult to tsuwm is straight out of Rostand (1897).

By all means, release your screaming urges!

Although these may not specifically be insults, a couple oldies but goodies: When someone didn't hear what was said or missed the key point they are told to " get the s**t out of their ears" or if you are caught bulls**tting Mom used to say "Your so full of s**t your eyes are brown!"
