Negative comments yielding positive impressions of neutral third party (girl, loving, attractive)

[Raging-Hetero]

Have you ever thought so lowly of an acquaintance that their negative comments about a neutral third party led to the development of a positive impression of said third party ?

Quick Example
Last week, after playing soccer with a couple of friends and acquaintances, one guy made a comment about how some girl who worked at the gym was a slob, because a couple ago, he saw her leave a house party with two guys in drunkin fashion.

I see the girl at gym all the time, but I never really noticed her. However, this douchebag's comment has changed everything. Now, for some reason, I see her in a positive light. I now think she's quite attractive, and I kind of like her voice. Tbh, I'm loving every new attribute I notice about her.

I know this resulted from the mere fact that I'm utterly disgusted by the guy's personality in general, and I probably didn't even bother to rationalize. You know, I highly doubt he's lying about the house party incident, but still....

Anyway, it just hit me that a fair amount of the positive impressions I have of people I relate and have related to platonically/romantically have come about in a similar way.


Questions
Has anyone ever being in a particularly similar situation, and do you think it's a healthy/good/normal way to develop positive impressions ?

Probably not a good way to develop positive impressions about people but rather a GREAT way to want to get to know the "third party" to see if it's true

I think its better to hold a neutral opinion of someone until you actually meet them and get to know them.

I don't keep acquaintances that I think lowly of... so I can't say...

I can't think of an instance of that in my life, but that has probably happened a few times. Kind of an "enemy of my enemy is my friend" thing.
