hey,

Are “My feet” and “My eyes” any slang expressions?

Hello Jraou,

Not that I know of. However, in British English, “My eye!” and “My foot!” are old-fashioned expressions of doubt or disbelief or scepticism, e.g.

A: “He said I should use Google to find examples of the phrase. I thought it was a very good idea.”

B: “Good idea, my foot! Google is full of bad English.”

Best wishes,

MrP

The same is true in American English. I’ve heard and have also used “my eye” or “my foot” the same way MrP described.
