Difficulty: Moderately Easy
Step1
Everyone appreciates a compliment about their looks, so if a stranger does pay you a compliment, there is no harm in smiling and thanking them. However, if they understand your nice gesture to mean that you want to hook up, gently turn them down by saying, "No thanks, I'm not really interested." Then walk away. Most of the time the person will respond by saying "Okay," and walk off.
Step2
A social outing to a nightclub or a party is one of the hottest places where hook-ups are created. Most women (and even guys) know that they will mostly be hit on by people that they are not interested in at first glance. If a person asks for your number and you don't find them to be "date-material," let them know that there are plenty of other people that might give them a chance at a date. They might respect your opinion and realize that you are right and move on to the next person.
Step3
Unfortunately, some people assume "No" means "Yes," and these types can truly get under your skin, as they try their hardest to make conversation with you. Not only it is annoying, but it is a turnoff because they seem desperate and can't take the hint that you are not interested. The simplest thing you should do is bluntly say that you cannot picture the two of you dating and, in extreme cases, tell the person to leave you alone or give them an angry glare.
Step4
Make excuses. Sometimes a little white lie is okay if you want to get the person off your back. Mention that you are already involved or that you just purchased a new phone and don't know the number by heart. You can also say that you just want to stay single and that you aren't looking for anyone at the moment. Most people will go away when they find out you are unavailable. They will drop the conversation and leave.
