This pose is known as 'dogeza' (土下座) in Japan and has a cultural background of expressing the utmost apology or request. In Korea, it's seen as similar to the 'keunjeol' (deep bow) culture and is also used to show sincere respect or gratitude.

In Western cultures, it might seem like an exaggerated expression, but it's often used humorously online. For example, when you're amazed by a teammate's incredible play in a game, you can wittily show respect by saying something like, 'Teach me your ways, master 🙇.' It's a versatile emoji that can be both serious and humorous.
