Ladies, why are there some "friends" who copy your interests (in men)?

I have had many friends who weren't interested in a ceratin type of guy, but will IMMEDIATELY "change" their interests when they discover my type... Why is this done? Is this a frenemy revealing themselves to me? For example, they go from saying "I hate beards" to "omg did you see his beard. so sexy".
