What do you call (a noun or an adjective) a person who keeps talking to someone despite the fact that they're clearly not interested in having conversation with that person? The most typical (but not the only) case I can think of is when a man is making advances to a woman who is not interested in him and thus he keeps trying to initiate a conversation with her over and over again.
The word or phrase should mainly express that this kind of behaviour is annoying. A person behaving in such a way usually does so because they fail to realize that they are not as attractive or interesting to others as they think. I'm not after any particular word or phrase - I just want to describe this kind of person or behaviour with as few words as possible. Example usages of the word or phrase I'm looking for could be (but are not to limited to):
- This guy is really annoying - he's such a ... / he's so ...
- Go on, send him a message!
- No way, I've already sent him several messages and he just ignored me. I don't want to seem like a ... / to be ... / to behave ...
The best word I've found so far is pushy but it doesn't really express the idea of starting a conversation with someone who's not willing to talk.
