Why SL Know Plug (born June 27, 1981 in Vienna; , formerly Money Boy, alias Mbeezy; born as Sebastian Meisinger) is an Austrian rap-singer. He became famous with his hit Dreh den Swag auf.
Money Boy grew up in the 15th district of Vienna Rudolfsheim-Fünfhaus. By 2008, he studied Journalism and Communication at the University of Vienna. He successfully graduated with the degree Magister philosophiae. His master's thesis was about Gangsta Rap in Germany. Before starting with rap, he played basketball for a long time. He initially wrote his lyrics in English. After his first public title, Ching, Chang, Chung, Money Boy caught attention in late summer 2010 after publishing his cover Version of Soulja Boy's Turn My Swag On, Dreh den Swag auf.
In 2014, he gained attention for his appearance in a live show on Swiss TV channel joiz, during which he recommended the recreational use of Heroin and MDMA at parties. Some of the Twitter messages which were contributed by the TV audience, and were read out on live TV by a moderator included ″Take drugs and rape sluts" and "I just took Heroin and I'm having a really good time"; regarding the latter one, the moderator stated that he "did not know if this is meant seriously or just a joke". One of the moderators also alleged that he urinated on the wall of the TV station building during a break. For that performance, Money Boy got an award by German TV station ProSieben. He attended the awarding ceremony, which was broadcast on TV, and recited his acceptance speech as a rap.
