Please have a look on the following video and let me know what do you call such a person in everyday speech and which verb can be used to describe his actions:
Based on my dictionary definitions, he can be called a "menace" and what he does is "menacing to the people"! But the problem is that the translation of these words from English to my language reveals that they are used for some more sereous meanings while what I'm looking for shold be a multilateral concept which can imply both humor sense and sereous aspect as well! I was wondering if English everyday speech encompass such words (noun & verb)! I would appreciate it if you provide me with some separated words to describe the funny and serious aproaches independently (if exist).
