Friends with Benefits is a term that can describe most anything. However, usually, when one talks about this phrase they are speaking of "a person with assets who can help the less fortunate person out" who is in need of money, property, a good meal, a favor, etc. This means that the friend in question likes to pay for things and in exchange, you put out for a little while. It can be a long term or a short term proposition. And, friend with benfits does not always mean putting out for sex in exchange for money. You can be doing this for other favors to that person, like for a meal, a chance to see a play, a chance to help someone get from Point A to Point B, etc. etc.
As an example, if I run an ad on Craigs List about friends with benefits, maybe this means I am looking for a good time but I am also short on cash so I would appreciate meeting someone who understands the term and a person who likes meeting a person like myself or whomever. So, in exchange for my spending a little or a lot of time with you or a group of people, it is "expected" that you are going to hand over some cash or buy me something that I need/want to satiate my needs/wants/desires. This is called 'friends with benefits' to put it lightly. I could run an ad in MFM or MFW or both looking for a person who has money on Craigslist or anywhere I wish to that is discreet, usually, lots and lots of it money they don't mind burning through to give money to me, the charity in question. This is just one example of 'friends with benefits'. There are many others.
