This is a gif extracted of an animated show, supposedly for kids, called Adventure Time, in which a young man, called Finn, tries to impress a girl to whom he feels appealing, a princess whose hair is made of bubblegum, hence her name, Bubblegum princess. The method of attraction he is using was suggested by Marceline, a vampire girl that we can see under the form of a bat, performing some moves which remember some sort or martial art. She is trying to communicate him that the girls love the action and, therefore, is a good idea to perform some fighting movements over the princess. We can see that he performs what he calls a "headlock" which reduces her and then, hit her in the back with his elbow. Meanwhile, his magic dog Jake, who can take any form he wants, is still apart under the form of a chair, and over him, something that seems to be a violin.
