The best things in life are free. Similarly, the best insults don’t require any curse words — regardless of how angry you are.
We’ve seen this all the time in popular sitcoms, like whenever Sheldon Cooper on The Big Bang Theory finished a cleverly crafted insult with the word, “Bazinga!” Or when Chandler on Friends told Joey, “You have to stop the Q-Tip when there's resistance!"
So the next time you’re ready to dish out a mean insult, consider these tamer (yet, equally savage) lines.
