Tis a fine insult and certainly has withstood the test of time. That said, "Twat" is by far the the most emasculating of the gendered put-downs. "Shut the f*ck up, you little twat". Roll that over the tongue a few times. Best said with a Boston accent.
The always priceless mystified look suggesting "What's a twat, Billy" is worth a thousand douchebags...
