でも・じゃあるまいし (demo jaarumaishi)

You're not that, so; since it isn't ~

Meaning & usage

でもあるまいし and じゃあるまいし express criticism that an action or expectation is unreasonable because the situation is not what would justify it, meaning since it is not ~ or you are not ~. It follows a noun directly, as in 子供じゃあるまいし or プロでもあるまいし, where でも often stresses not even being that thing. The tone is blunt and reproachful, common in spoken complaints or scolding, so it can sound harsh toward the listener.
