📖 Definition of the word "Beauf
The word "beauf" has two meanings. It refers to someone's brother-in-law in a very colloquial language (c'est mon beauf = that's my brother-in-law), and it also refers to someone who isn't very distinguished, who lacks class or good manners. It's a rather pejorative term, not to be used in front of just anyone.
Note that it's a very subjective term, depending on who's using it. For example, one person might consider someone to be a "beauf", while another might not. In France, it can be quite frowned upon to refer to someone as a beauf, as it can make you seem pretentious.

"He's such a hunk, he spends his life in the weight room".
"What a hunk, he wears socks with his flip-flops"

Once again, the term "beauf" can show that you think you're superior to others, so think twice before using it.
👩🏼💻 Use in a professional, formal environment
It's a word not to be used in a professional context, except with work colleagues you're quite close to. But if in doubt, don't use it, it's probably not appropriate.
