it is kind of on the shut out? what does this expression mean? thanks:)

If something is ‘on it’s way out’, it means that it’s becoming unfashionable or unpopular.

The idea is that something is on it’s way out the door, i.e. leaving.

I don’t think there is such an expression ‘on the shut out’. That’s why your answer was marked ‘incorrect’.[YSaerTTEW443543]

Hi,

Just a nitpicking comment - it should read ‘on its way out’.
