The tip comes from a bloke called Jonathan Massaad, a baker and avowed McDonald's aficionado who has devised a simple way to customise your burger to maximise the experience.
It's simple really, and you don't need anything else, just an ordinary Big Mac sandwich.
The 22-year-old claims that by taking off the top bun, then grabbing the middle slice of bun and the top burger and flipping them upside down, you can elevate the flavour by increasing the 'meat-to-sauce' ratio.
As you are no doubt already aware, the bread within the centre of the Big Mac is slathered with a liberal helping of the famous Big Mac sauce.
The top bun, which is no longer necessary, has no sauce on it and can simply be discarded as useless.
According to Jonathan's presumably extensive research, turning that over can increase the delivery of that sauce, which can only be a good thing, right?
Describing it as 'the best Big Mac hack ever' on his Instagram account, he explained: "Take the top bun off, get the middle and flip it,
"Now your meat and sauce ratio is a lot better because this bun has no sauce - and now this has all the sauce."
Now, some of those who've seen his tip have suggested that he could simply ask for more sauce on the burger, but where would be the fun in that?
One fellow Instagrammer also pointed out: "It beats the purpose of the three-layered bun."
It seems as if Jonathan isn't the first person to have discovered this trick, with many other folks piping up to say that this is a tried and tested method.
That might just lend it a bit of credibility.
One such person said: "That's old school - I've been doing it since I was a kid!"
Jonathan usually uses his platform on social media to extol the virtues of Cake Mail, which is a cake delivery service that he runs in the Australian cities of Melbourne and Sydney.
However, even if you're not based down under, you could still give him a follow to learn about some of his more leftfield food experiments.
Next time you head on down to your local Maccies - or Maccas, for the Aussies out there - give this particular tip a go and see what you reckon to it.
Jonathan is certainly lovin' it.
