Peertje 

This is a high class of mage. They have multiple ranks form high to low, to get higher you need to win your kahoots man, the lower class is peer, this is when we don't like you and you will probably be assassinated, above that is peertje, this is used as a curse word when someone is being clumsy or just a fucking normie, above that is peertje.(insert something here), here you can choose a word of what you like, nice memes, this means that we like you, keep it up, papi is proud, above that is peertje peer, to acquire this rank you need to have won at least one kahoot, congratulations, the highest rank until now is toffe peer, then you are the king of the peertjes, but this has never been reached, you need to have a kahoot streak of at least five times in a row, almost impossible! To join us: you can't, fucking cunt. Omae wa mou shindeiru.

"NANI!!???? What a peertje!"
"Omae wa mou shindeiru. FUCKING PEERTJE!"

Petertje 

Its the way you roll a cigarette/joint, when your cig is all bended and stuff, way too small, you've just rolled a Petertje. Normally, the persons who roll Petertje's dont really care about the way their cigs look, as long as they're smokeable.

He rolled a Petertje, cuz he was in a hurry.

She is a worm with class. A great person who looks always on point. You should have a Piertje in your life. She’s like a guide. Follow her advice.

Person one: Is that Piertje?
Person two: Yeah! You should follow her on Twitter: @PiertjeTV
