turd in your pocket

Part of a sarcastic retort to someone who speaks in the plural form, when it's been commonly understood that they really mean it to be you.

When someone tries to include you in a "we" that you don't feel part of, the traditional response is "We? What do you mean, we? Do you have a turd in your pocket?" Translates as semi-funny emphatic rejection of false or forced collectivism. (My "do you have a mouse in your pocket?" is the cleaned-up version of the old rhetorical rejection of the false "we.")

What you say when someone wrongfully assumes you will be included in an undesirable activity. Another way of saying "what do you mean we?"

A sarcastic expression used when a person uses the word "we" when they should have actually Used the word "I." Or when a person says that "we don't" do something that at least one person is actually doing. This expression is used to totally catch the offender off guard, rendering them incapable of coming up with a response to the awkward comment.
