Wet seal is basically when you slap a girl in the face with your semi-hard dick. Variations include a facial THEN a wet seal, or a wet seal followed quickly by another wet seal in the other direction. Whenever wet seals are performed, they must be declared. You must let the person know that they have been wet sealed. This also applies to the non-literal definition of wet seal in which you just make someone look like an idiot.
You've just been wet sealed!
