just tell her you're not interested. even if it's overkill...it will work.

Yeah..I'd say just telling her you're really not interested should work. Or maybe make her cry somehow by telling her she looks bad or something, then she'll hate you.

nah that won't work. Making her cry, telling her she looks bad.. that IS a relationship. What you should do is just say " I dont date fat chicks" then proceed to grab the side of her stomach.. ...
