If you want to say TMI differently, you can use phrases like 

• Overshare 

• That’s a bit much

• I didn’t need to know that 

Other slang terms include Way too personal or Keep it PG. In texting, some people use emojis, like the shocked face (😳) or facepalm (🤦), to react instead of saying TMI meaning directly. These alternatives keep the conversation fun without being rude.
