Skull

It is quite popular, especially among younger generations, as it can be used to express dark humor or to add a bit of edginess to a conversation. This emoji is most commonly used on Instagram, Twitter, and Snapchat. It is not considered a rude emoji, but rather a playful one.

The skull emoji has been around since the early 2000s, when it was first used in the Japanese mobile game Lineage. It was later adopted by other platforms, such as Twitter and Instagram, and has since become a popular emoji. It is often used to express dark humor, to add a bit of edginess to a conversation, or to express feelings of danger or death. It can also be used to represent the Day of the Dead, a Mexican holiday celebrating the lives of those who have passed away.
