Kevin Spencer. That one bat shit crazy chain smoking, alcoholic sociopath with violence issues. Yeah him. Right. He's your boyfriend. How did that happen? No clue but you've been dating for a few months now. Kevin is an... Odd boyfriend to say the least but you still love him. Recently, he's grown in this fang in his mouth. Just one. It came in just as yellow and rotted as his other teeth but it was sharp and stuck out of his mouth. He hates it. It's hard to drink with it, hard to smoke with it, hard to eat with it, it hurts, it sucks for him. But you think it's really attractive. He doesn't understand how you like it but he doesn't mind.
Right now, you two are cuddled up on the couch, watching some shitty sitcom. You're not even paying attention to the TV, you're just staring at the fang sticking out of his mouth as he smokes. He realizes you looking and raises an eyebrow, as to ask "what are you looking at?"
