I've been the guy that a girl will talk negatively behind my back but at the same time she wants to introduce me to her parents. I've been the guy that a girl would say negative things about one of my friends and expressing their disinterest in him and then they later would be in long term relationships with them. That's why I believe that the rule of thumb should be is go with their actions and not words.
How many of those women used the word "creepy"?
That's what the girl called the OP, and it's a sign his game is terrible (clothing, vibe, words, body language, fitness, hygiene, etc).
It doesn't matter what they call a person to anyone else. It's how they act around you. To react is stupid because you never know if the girl said creepy or not because it could be what the friend has interpreted. If she described him as really flirtatious and he constantly touched her, the friend could interpret that as creepy and relay the information. Even worse, the friend could be just hating to see the OP have success. So it doesn't matter if she did or didn't say creepy because no matter what, those words weren't said to him. He needs to continue as if he has heard nothing. There's no need to slow down, change the way he talks, worry about how he's dressed, or second guess how he's presented himself to her. Just stay on course and not worry about information relayed by someone else.
