Meet him, if you don't like him then make an excuse and leave early and later tell your friend that you DID meet him. Done
Idea for excuse. Have another friend ready with his phone. While meeting the guy, if you don't like him, casually send a message to the waiting friend, he'll call you and tell you to come over and have the meeting/visit you promised(FAKE). You leave saying your really sorry. All is Well!

Thanks, i did this and it turned out he was a total Weirdo, thanks for the advice
