Mate-Peng is commonly in germany for a combination of two drinks; Mate and often times alcohol like Vodka. It is used more often but similarly as the word Turbo-Mate.
The combination of words comes on the one hand from the drink "Mate" which is a popular caffeine drink amongst students in germany and the Word "Peng" which can be translated as "bang". This part of the combination can be explained by the german idiom: "... mit Schuss" which means something with alcohol. But can be directly translated as "... with a shot" (in this case it comes from the word "to shoot"). And since a shot makes a "bang" noise or a "Peng" noise it is called Mate-Peng
