Okay, so @Danidee wasn't sure what broscience was and I didn't realize that it might be a term that not many may be familiar with. I guess I have been a bro such a long time...
A term used to describe misconceptions and ideas of questionable scientific credibility. It's basically bullshit knowledge. It's usually "facts" that have been passed down mouth-to-mouth with no actual backing.
Examples of broscience:
"If you eat carbs, you'll get fat."
"You can turn fat into muscle."
"Protein powder is basically roids."
