Nerdy Fuck Boi. - typically a whiny ass skinny ass piece of shit who grew up a nerd got a little jacked started having some aesthetics and now thinks he knows and owns everything.

Likes: overcompensating, projecting his insecurities on his partners, making other people responsible for his happiness

Dislikes: people with real confidence, feedback of any kind, being told no
- Back in high school, Jeffrey was a nerd. To compensate he started watching some broscience and lifted, and traveled to Paris or some other European artsy city. Now he think he's cultured and his opinions are the end all be all.

He a NFB.

- David didn't get chicks in highschool because he was weird and insecure. Now that society is more accepting and he's a little more cute, he thinks it's cool to treat girls like garbage and passes it off as modern romance. Yet he's a "feminist" and ally.

He a NFB.
