parking ramps

Usually, one is forbidden to park or walk on a parking ramp. The French verb that ramp comes from means 'to rise, rear up'. There is a verbal meaning of ramp in English of which I was unaware: ramp 'to act threateningly or violently; to assume a threatening stance' (link), thjough I knew of the accompanying adjective form rampant used in heraldry of quadrupeds rearing up on two legs.

Ceci n'est pas un seing.
