Sisters of Mercy

Best band ever, and just because they helped define a genre, doesn't mean that listening to them makes you a poseur.

As in: The Sisters of Mercy are THE BEST BAND EVER, and I listen because they're GOOD, not because I want people to think I'm tragically goth.

your sister a mister

your sister a mister is possibly the worst insult ever created. It will destroy an entire dimension whenever it is used. Another language had to be made to create this phrase, and this is the rough translation. Calling someone's sibling trans is easily worse than Your mom gay, Your dad lesbian, Your granny tranny and Ur grandpap a trap are hardly insults copared to your sister a mister.

God: Are you a little bitch?
Me: Your sister a mister
God: *Fucking dies on the spot

Shifter

Also known as a shape shifter, shifters have the ability to shift into any form or animal. In most stories or myths, the number one form for a shifter to use is a wolf. They slightly resemble werewolves, but don't unwillingly change on a full moon, in fact, the moon does not affect them at all.

Callie was very bad at hiding the fact that she is a shifter.
