1. Ignore the Guy Totally.
Ignoring the guy seems one of the first simplest way of saying "am not interested" but if he tries to stare at you or even pose to have a relationship with you, then you need to come out so frankly and address him in a matured manner. Do not be silly or he will never take you serious. Since it is so common for guys in particular to stare at a lady, always learn to ignore stares or whistles rather than shouting or acting lower than your personality.
2. Be Nice to Him.
Being nice is one of the sure clever ways to make someone do what you want. Get closer to him if you can in order to bring his mind to a quick emotional conversation. Do not try to utter rejection in an instance, but keep cool and act friendly.
3. Be His "Friend".
One of the most cleverest attributes of some wise girls is keeping creepy guys on the friend zone. Most of the times creepy guys may be satisfied just to be talking with you from time to time. So even when he tries to escape the friend zone, be nice and show him the way out of your life. If he insists you need to get a proper reason of rejecting his proposal without being aggressive. Letting him know that you're in a relationship is nice, not ready for now. If he still insists, just avoid him totally and pretend he doesn't exist at all.
4. No Option? Transform Him.
Sometimes, even the nicest of guys can turn out to be creepy guys. Since we are talking about what to do when a creepy guy loves you it is also wise if you can take the time to make him handsome. I understand that creepy guys are not that so bad and with care and simple mind to mind advice you can get them transformed forever. So if you can't avoid him change him to what you want, but if he can change the next time he says "hi" to you shout on him irritatively and he would live you forever.
5. Stop Attracting Creepy Guys, He'll Leave You.
Stop talking dirty. If you enjoy talking about creepy things, surely you can never get away without having a creepy buy following your trail. Know how to act when you're around guys to get yourself quantified of the obviousity that follows a silly minded lady which usually brings bad luck. Do not be fun girl. Avoid making many older pals. As a whole, avoid making friends everywhere in the sense that you don't look like someone simple to fratenize with. Lastly, dress decently and the lust side creepy guy will do away.
