The term RESPONSE TO AN INSULT can be broken down into three crossword solutions: SLAP (4 letters), OUCH (4 letters), and EXCUSEME (8 letters). A SLAP is a physical response to an insult, usually done in anger. It is a form of aggression and is not recommended as a way to handle insults. OUCH is an exclamation of pain or surprise, often used when someone has been insulted. EXCUSEME is an expression of apology or regret, often used when someone has said something hurtful or insulting. All three of these responses are common reactions to an insult, but none of them are ideal ways to handle the situation.
