In a Family Guy's episode, Season 3 Episode 13, Peter starts acting politely and behaves himself in his father-in-law's party also trying to act like the rich and blend. Suprised by this, Lois's father asks her how this happened and she replied, "he's cultured himself like Julia Roberts in Pretty Woman." I've checked the meaning of culture in verb sense and found a couple of definitions that I'm not sure exactly which one fits the context esp. with a reflexive pronoun after the verb and considering that Peter doesn't really like his in-laws. If you want to paraphrase this sentence how would you go? Is this standard using of the word culture or simply an improvisation here and not a common usage?
I would say is an improvisation. The word culture isn't generally used as a verb in this context.
As a paraphrase, I'd suggest:
He's decided to become a more cultured person.
I would paraphrase it as:
He's cultivated himself.
- To acquire, develop, or refine, as by education: cultivating a posh accent.
Interesting question, I think that integrate is often used with a very similar connotation;
to mix with and join society or a group of people, often changing to suit their way of life, habits, and customs:
- He seems to find it difficult to integrate socially. It's very difficult to integrate yourself into a society whose culture is so different from your own. Children are often very good at integrating into a new culture.
It is an improvisation, with the meaning "He has made an effort to become cultured." Google search throws up just one additional example: "He's cultured himself in all types of music."
It sounds a little patronising, so don't use it at home.
