'Lockerroom talk' is one of the most cynical ideas in our modern politics. Every guy knew a guy in the locker room that talked like that, but we didn't invite them out on Friday night because they're a gross embarrassment.
There's some confusion between "popularity" and social status/power. I will venture that the "popular one" you're talking about was a high-status dude who was allowed to get away with talking like that because other boys sucked up to him for reasons such as money or clout... not a genuinely well-loved friend who earned his popularity by advocating pussy grabbin'.
If where you come from, the way to people's hearts is talking that way, sounds like you had a... lovely upbringing
