A man's viral video breaks down why women may not prefer 'nice guys.'

The term 'nice guy' often describes men as agreeable, gentle, sensitive, and vulnerable, but it can sometimes carry a negative connotation of being unassertive.

On the flip side, 'macho' men are seen as lacking kindness and sensitivity. TikToker @cyzorstudio delves into the issue, highlighting a fundamental problem: the expectation of niceness from the outset.

Here's his explanation: "Expecting women to want you because you're a nice guy, it's like expecting women to want you because you shower regularly."

"You shower regularly, right? At some point during your childhood, somebody told you that if you want a girl to like you, all you have to do is be nice to them."

The TikToker further emphasizes that simply being a decent person isn't sufficient to attract a woman.

He elaborates: "Let me break this down for you. If you're feeling bitterness, that means you feel like you deserve something and you didn't get it, right?"

"You feel like you deserve her, right? Because you're so nice, yeah? No, stop being entitled."

"That's not how any of this works. Sometimes you'll put your best foot forward and someone still won't like you because they just don't like you. That's life. Being bitter about it is childish. Move on."

Viewers have wasted no time in expressing their thoughts on the matter, with one individual commenting: "If you have to tell people you're a 'nice guy'… you're not really a good person."

Another user agrees, writing: "Sign of weak character, to stand on the 'nice guy' platform."

Meanwhile, another individual chimed in, hailing the TikToker as "a gift to the internet" for his insightful perspective.

"This may be the most accurate thing I've seen on IG ever," another commenter expresses.
