Qualitatively and quantitatively, what is your definition of/benchmark for "F U Money?"

It seems I struck oil yesterday about not giving a rat's ass about work after a given amount of time. It also seems this sub agrees $3.5 million is the consensus benchmark for FI/RE, per another post from earlier today. With that, I want to reconcile these two posts and ask what the consensus benchmark for F U Money is on this subreddit, and why why think so, and with that what the technical definition of F U Money should be. 

Just my reading from various sources, it may be the case that "F U Money" is defined as having enough funds to quit a job without another one lined up, and still plan on landing another one down the line (perhaps a 6-month emergency fund). It may also be the case that one may define such as having enough funds to quit a job and never have to work again (that is, a state of outright financial independence). I am interested in this subreddit's thoughts on the matter as I think it would benefit us greatly in developing a consensus definition and benchmark for such.
