Maastricht University 

In a few words: International university, Germany central, nerds central, dutch frat guys central, PBL method, bikes infested.
The only university capable of driving its students into nerds. Even the hopeless ones.

No matter where Maastricht Uni students have studied before/afterwards, UM will always remain the hardest one for them.

Maastricht university is so hard.

maestrobater 

To conduct your penis as if you are conducting a symphony orchestra, usually to classical music.

"Don Tildone was quite the maestrobater."

"Too bad they banned the vid of him on YouTube."

"Well, it was pretty inappropriate when he ejaculated into the trombone section. Then the entire audience had to wait for fifteen minutes while he warmed up again."
