🚫 Nicknames to Avoid

While nicknames are meant to be fun, some can cross lines. Avoid any nickname that:

• Mocks Appearance: Comments on weight, height, skin color, or physical features can cause lasting harm.
• Attacks Intelligence: Names implying someone is stupid or slow are hurtful, not funny.
• References Trauma: Avoid nicknames connected to painful experiences or insecurities.
• Uses Stereotypes: Racial, ethnic, or gender stereotypes have no place in affectionate naming.
• Feels Forced: If someone clearly dislikes a nickname, respect their feelings and stop using it.

The best nicknames lift people up, not tear them down. Always prioritize kindness and consent.
