hitting on

"A man being polite to a woman," flexibly given an undefined negative conotation by the speaker if he is annoyed by the fact of the socialization but couldn't find any specific wrong to quickly point out. A "fudge word," used to describe the action or inaction of a man who is as a man deemed to be the responsble party, to mean an inappropriately close communication or socialization between a man and a woman. "Socializing," which is a positive word can be flexibly described neutrally and romantically as "flirting," or negatively as "hitting on." Can also mean "hitting," thus further demonstrating the flexibile nature of its meaning.
