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.
It is a waste of time to try and classify all of the bands in the world but if you did most of the good ones would come under the group heading of METAL.
Punk (im talkingh real punk, not 'my girlfriend left me' shit) is kind of like metal except with most of the goodness talken out and replaced with Dee-dee Ramone (who has a face so hideous that when he looked in the mirror he died) and is therefore rarely ever good.
Dark Throne is not metal, see its definition for details.
'Heavy metal is the law'
'I am quite gay, i am going to listen to some non-metal'
