Five Geek Social Fallacies
Basically, not everyone needs to be friends just because they share a hobby. In this case Flumph was brought in by a friend (strike one, he didn't understand the incompatibility) and then said friend left him with you and you endured it (strike two, you didn't discuss the problem to begin with). This translates to fallacy #4 and fallacy #1 in my eyes.
While it's not Flumph that has committed these fallacies (he might have committed #2 , though), there is no duty to endure him. It might be incompatibility, like you've said. He might not be a bad person, that is. But it's a good enough reason if you judge it not worth the effort to fix.
Our group endured a resource-grabbing, foul metagamer that always played the same CE character in different guises (Not literally. He just always played the same way.). I and our current DM got very tired of his presence and when he starts his next campaign, the player will not be informed. We've always worked by the principle that people are summoned to take part in campaigns and said player has not been part of all campaigns we've played. I haven't asked him to play in my games in a year already. He's still got other company to play with but we're simply incompatible with him.
Oh, and unlike the OP, I'll give a few examples to avert critique due to inadequate details.
1. He eats greasy foods with dressing and prefers to use the pencils and dice of others. Once he slipped his hand in an Uncle Ben's jar, grabbed the rest of the sauce and licked it off his hands. And then he tried grabbing people's dice. We seriously told him to go wash his hands.
2. "My character's not chaotic evil - it's chaotic to randomly mug and kill people and neutral to be selfish." This was his about his Warlock that was not sharing the loot with my dumb tank character and whose idea of a good plan involved torture, larceny and murder. Oh, did I say these were the attributes of his character? Pardon me, I meant the player: since the character was used as nothing but his personal avatar in the world. It had no personality of its own whatsoever.
3. Whenever we undertook or completed a quest, he would haggle about the prize. Hot damn, he even tried to negotiate with overzealous Paladins that were making it very clear that they'd let us go since we did them a huge favor but people like us would no longer be welcome within city borders. And the things he tried? Essentially Intimidating them to give us a right to stay. That's just damn stupid but he'd grab any opportunity to try and enforce his personal will.
