Get the Bastiaan mug.
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.

He is a great and loyal friend, he will not leave you alone in difficult times. He will tell you clever jokes here and there that will make you laugh a lot. Bastiaan has the best ear ever, music is his thing, he will recognize melodies in random songs that you are listening to. Friendly and very patient. He is good at many things, lately dancing.
