Sure, men will make a comment about a girl who has a reputation for getting around, but they won't exclude them from social gatherings or events. In fact, they're more likely to invite the so-called "slut" because she knows how to have a good time.

On the other hand, women call other women sluts extensively, and will judge girls and ostracize them based on their dress or sexual behavior. This is why women often will go back to their friend groups, despite probably being willing to go home with a guy. Women often use sex as a bargaining tool for commitment, which is why the slut threatens them. She devalues the value of pussy.
