Gamblecore is a Flipnote animation by artist raXd in which someone excited to go gambling loses successively and in quick fashion while playing a slot machine. It became quite popular out of its niche circle of Flipnote animations as many people used the audio to make their own versions with other topics that one may ‘lose’ at. The quote “let’s go gambling” is a distinct trait of the animation that has become widely popular.
