Someone who is extremely good at manipulating and deceiving people for their own selfish gain. Examples of Machiavellians include, but are not limited to: IRS scammers, sugar daddys, e-girls, e-prostitutes, black hat hackers, Donald Trump, your girlfriend (potentially), sketchy sellers on Aliexpress, and that guy down the street who claims he is homeless.

If you are a Machiavellian, please do take note that machiavellianism begets machiavellianism. Research has shown that people who have been psychologically manipulated are more likely to manipulate others.
Dude 1: So I heard you bought some custom videos from this e-girl on Reddit, how'd that go for you?
Dude 2: Extremely bad. I thought she was legit and everything, she even showed me a screenshot of the video, but once I had paid her she never replied back.
Dude 1: Damn dude, I mean I wouldn't have trusted some random internet girl in the first place. The online sex market is filled with Machiavellians, y'know?

A conscious delay in response for the purpose of not appearing too overly eager to respond.
"I reject the concept of a Machiavellian delay. I think social networking has made this tactic transparent. The new ethic is authenticity, which lends itself to fluid communication."

A reopening that makes people feel a sense of morale boost, like they are the ones benefitting from stores, businesses, and restaurants not being shut down anymore. Somebody starts a petition and all of a sudden everything is open again, yet nobody is questioning whether the one who started the petition might have had something to do with everything shutting down in the first place.
The girl was the one to start the petition that reopened everything. That is a lot of power for one person to have. Wouldn't it take the same kind of power to have everything shut down as well? It seems more like a Machiavellian reopening than a true morale boost.

Some people say they beat a case in court. There is no such thing as going to court and beating a case, you're still going to lose money every time you enter a courtroom even if the DA/prosecuting team isn't guaranteed a conviction to go on your record, if you haven't already served at least a few weeks in jail for a charge you didn't get convicted of. As long as the machine/system is what you're fighting, what you call a win or beating a case is really just breaking even by not losing everything, and you're always going to lose at least some of your money to part of the machine/system, no matter what. Though that would discourage a lot of people, it doesn't mean that no fight is worth fighting, even if there is no winning in the end.
Machiavellian Victory is a struggle with a Machiavellian force (a Machiavellian prince or princess, a part of the machine) where you don't lose everything for once.

A manly princess. Not to be confused with a true tomboy that does things guys do, a Machiavellian princess appears/seems to be a tomboy or like a tomboy on the surface, but is actually excessively masculine by nature, and someone you would think would have had a sex change by now, but hasn't done so only for fear of the social stigma. A Machiavellian princess is called a Machiavellian princess in the same way an effeminate prince is called Machiavellian, she is the female version of a Reptilian effeminate prince.
The Machiavellian princess wants everybody back in line.
