You might have heard of 'big d**k energy', but have you been introduced to the so-called phenomenon known as a 'hung smile'?
Apparently, a toothy grin can tell you a lot about what a fella is hiding in their pants - according to people on the internet, that is.
We don't just have to take the word of social media users for it, though, as thankfully, a urologist has now shared his thoughts on the validity of the viral trend.
Men's health expert Justin Dubin - who specialises in male infertility and sexual medicine - offered his opinion on whether having a 'hung smile' is actually a thing.

For those who don't know, internet users have been using the term to describe a man who has a certain kind of smile which suggests they are packing heat in their pants.
It's a sort of sexy, smug, and self-assured beam that leaves you absolutely sure they are hung like a horse... so folks online say.

According to Urban Dictionary, the definition of a 'hung smile' is: "The effortlessly confident, self assured smile of a man with a large member."
As we mentioned, it's sort of in the same vein as 'big d**k energy' or BDE, a phrase which was popularised when speculation about the size of Pete Davidson's was rife.

According to Dubin, a hung smile 'is the facial equivalent' of this.
The Florida-based urologist and podcast host previously told Slate why someone might be described as having a hung smile: "If you have a perceived larger penis size, you’ll have a more favourable image to yourself.
"Because you’re more confident in yourself, maybe you do have a big d**k energy because of the fact you believe you have a bigger d**k."
So, it seems it's more about the massive kn*b vibes you give off with your grin, rather than your smirk actually alluding to what size your willy is.
The urologist explained that the size of a bloke's nose, finger length or butt would give you a better idea about how big their manhood is, rather than their smile.

However, there isn't much scientific data to support the idea that certain features reflect the size of a man's todger, so you're going to have to find out the old-fashioned way, unfortunately.

Dubin said measuring it is the only definitive way to determine how big a penis is.
"I’ve seen more penises than 99 percent of people, and I have no idea [of how big it might be beforehand]," he said. "I cannot predict what anyone’s penis size is when they walk into that room."
And if you are lacking a bit in the private region, he suggested using the 'hung smile' craze to your advantage - by giving the world a grin which leaves people completely convinced you've got something down there to smile about.

"Believing and acting like you have a big d**k, people will think that you do," he added.
He explained this point further in an Instagram post about 'hung smiles', saying: "To me, a hung smile is the facial equivalent of big d**k energy.
"The best advice I can give to any guy wanting to demonstrate BDE? Carry yourself like you’re packing. Or as the great George Costanza once said: 'It’s not a lie...if you believe it'."
