Is there any difference between "put one's foot in one's mouth" and "make a slip of the tongue". These sound pretty similar to me.

I put my foot in my mouth.
I made a slip of the tongue.

How do you differenciate them? Thank you in advance.

Answer

They are different.

I put my foot in my mouth. = To say something foolish or embarrassing or tactless.

I made a slip of the tongue. = To say something by mistake, perhaps revealing a secret.

Answer

All I can say is
“ putting your foot in your mouth”  is  saying something in a rude and unsubtle way.

A slip of the tongue is often unintentional. And possible more subtle

Answer

Foot in mouth? First of all gross, second of all what happens if you choke?
