he was probably a loser to snort. what a turd.
My friend was the same way and she got so sad about it ( I thought she was perfectly wonderful before though). But she started making daily routines for herself. She joined beauty school so she could learn how to beautify everyday and she eats absolutely no junk food. Now she’s gorgeous and sometimes a little too aware of it /: But I’ve never seen her self esteem so high and now she’s moving out of her parents and nabbed herself a hottie boyfriend that all the girlies want.!! Good luck!

apart from the “turdness” factor, if the guy is younger than 25 and/or has a reason to have low self-esteem (be careful about that, low self esteem can have reflections like conceit of the kind you pointed out) the snort could actually mean that he could think of no “cool” answer for the question that would not make him look or sound less “awesome”... i’ve had such cases when the loser finds his way back in literally weeping… and what kind of a person snorts when he is asked a question like that?! being hot has nothing to do with guys drooling over you honey, but it sure does feel good!
okay the first thing you gotta do is to get a good body, lose weight if you need to, invest in good underwear that accetuates your curves and all, be stylish but don’t exaggerate it, wear makeup that makes your skin glow and looks like it isn’t there at all, find your ideal hair style and stick with it no matter what, always be perfectly groomed, clean, fresh, feminine and smooth..these are the basics but they don’t work without the attitude.. the key is to ALWAYS be upbeat and positive about things and act like you don’t care what people think of you, because, you know, it is unimaginable that people would find you unattractive, like that is so out of the question that it doesn’t need any attention.. like you are at peace with anyone, but above all with yourself, and like you really love to be yourself and by yourself… Like you are essentially a very fun and happy person… (well you most probably ARE a person like that but if you feel like you are not, acting like that will help you realize that you are so.)
And about that loser… I’m guessing you would want to have him pay the price of that rude dismissal of a snort.. well if you’re not on bad terms with him act friendly and non-chalant (non-chalant and breezy are important !), as if he was just another friend.. this mood change would drive him crazy and if he is really an insecure loser in disguise, his mind would start nagging why he no longer is the center of attention, making YOU the object of desire.. don’t give in too soon or you’ll lose your inaccessibility, thus your charm where your hotness lays! tried and proved! good luck! ; )
