As written "eres mojada" doesn't really mean anything in normal conversation. It would mean "you are wet" in an existential sense, like if you were affected by some chemical and no matter how hard you tried or how long you waited you would eternally be moist. In a few communities, it is also a derisive term for someone who crossed a border of either a river or ocean illegally, very similar to the English term "fresh off the boat" but without the cultural baggage of that term.
