This creepy weird ugly fat kid has a crush on me! I always see him stare at me, he gave me his #, he seems to be wherever I am now, he butts his way into my convos... He tries to get me to call him 'Victor'. What do I do to make him stop?

Tell it to him straight, but tell it to him nicely.

I'm surprised he has a crush on you considering how unkind you are.  This "creepy weird ugly fat kid" finally worked up enough courage to approach you - courage is something you know nothing about - and you feel you need to serve his heart up on a platter and feed it to the wolves.

He's probably been bullied all of his life. Would it kill you to talk to him? Would it kill you - after you speak to him for a few moments - to tell him thanks, you are so flattered that he likes you, but you're not really into dating anyone right now. It won't kill you to listen to him when he tries to talk to you.

You will certainly not be the girl for him, since you are so caught  up on looks and not personality. However, giving him a few moments of your time will help him more than you think.

So the next time you feel like being childish and immature about someone's looks, think of how they feel when people like you make fun of someone like him.
