Laughing at someone's expense
Deceiving someone is hurtful, degrading, and abusive. When you're the target of put-down humor, you may try to shrug it off for "being one of the boys". In case you're the one getting laughs at others' expense, you may not realize how nasty you have been revealed to be. Look inward and ask: what does it get you? does it make any positive difference that you are hurting someone else?" Gain respect by laughing at yourself instead.
