if a person who has no money if it ends to be rich equals fake ballin
then what is a person who has money and pretend to be poor?
what's the term for that?
I don't think there is a term for something like that, and I question the validity of "fake ballin'" as well... I suppose it would be similar to a "shark," where someone pretends not to be able to play a game well but actually can in order to win lots of money. Closest thing I can think of.
If you go to somewhere like the Philippines as a foreigner you have to pretend you have no money whether you do or not. The general assumption in places like that is that you are rich simply because you are a foreigner. It doesn't matter whether you are or not it will be assumed that you are rich and therefore fair target for any and every scam that is about.
I thought avaricious meant greedy and I would say a rich person who pretends to be poor wouldn't be greedy. It depends on his intention behind the deceit whether one should use positive adjectives or negative adjectives to describe him. In any case, I can't think of one word as of now. Would "thrifty" fit actually?
