This study aims at investigating the types of slang and finding out the functions of it that used in Mr. Bean's videos. So, for this study, a descriptive qualitative research approach was employed. Slang is generally known as an informal style of speech which is used in a particular community by a specific group of people. The slang of the past is different from the slang of today. However, some slang has survived into the modern day (nowadays). The main objective of the current research is to analyze the meanings of various slang languages. It also attempts to analyze how words are formed in slang. Consequently, this research uses the theory of Keith Allan and Kate Burridge (2006) to identify the five types of slang and classify their functions. The results showed that there are four types of slang. They are Acronym, Blending, Clipping, and Flippant. The most dominant type of word formation - processes is Clipping. Most of the abbreviations have vulgar and rude meaning. To sum up, slang forms are spreading rapidly, and the majority of them do not last for a long time. People must consequently keep up with developments to understand the meaning of slang.
