A perverted, fake-ass, manipulative bragging male supposed to know his limits when communicating with his female students. Using his powerposition to get girls, twotime them and then silence them.

A young boy acting like he is woke and all girls should deserve equal rights, but in reality it is just to get them in his/their bed.
Omg, you're such a Bastiaan.

He gives me such Bastiaan-vibes.

Don't be like the average Bastiaan, bro.
