re: "Pick me girl" good or bad?

A “pick me girl” is a girl that is perceived to be seeking out male attention.

In other words, a girl.

Low status girls use the phrase as a dig against prettier girls who are better than them at playing the game in the hopes of tricking men into pursuing her instead.

Low status men use the phrase as a disqualifier to justify not approaching pretty girls they want but could never lay.

It’s a dumb phrase used by low status people to cope that they can’t compete with hot girls. Best ignored.

The phrase is implicitly liberal in my experience, the same way that “partner” for your wife/gf is—it doesn’t have any inherent political affiliation but it’s just more often used by liberals in my experience.
