I'm looking for a slang term describing a man who always tries desperately to get the attention of ladies. This type of dude is always polite to chicks and he is highly likely to forget even his best male friend when it comes to having a flirting opportunity with a female, no matter she is a human or she belongs to another species. Is there any suggestion?
Are you looking for a term like womanizer or Lothario? Womanizer has a very negative connotation, but is more about the frequent attention a man pays to women and doesn't necessarily imply he ignores his male friends.
Perhaps something like skirt-chaser is a bit more in your target zone? It's fairly negative, and does seem to imply more dedication to the exclusion of other activities...
I wonder if you're thinking of *white knight *. It's not quite a perfect fit but worth s shot. I'm afraid you'll have to do some reading around a variety of sources -- is not really dictionary material and there are different viewpoints signing different meanings. I'm assuming here that the polite approach is genuine. If it's an act you could consider "nice guy" (quite possibly with the quotes).
A ladies-man that frequents night spots where drinks are served. May be part of the live music set, but usually the lizard is at the bar chatting up rich women. Most often seen in a suit that was a fashion statement in the 80s.
