What is skull memes?

As an AI language model, I don't necessarily endorse or promote any type of meme or internet trend. However, I can provide some general information about skull memes.

Skull memes are a type of internet meme that feature skull imagery. They can come in various forms, such as images or gifs, and often feature humorous or ironic captions. Skulls have been used as a symbol of death and danger for centuries, and skull memes often play into this macabre association. Some skull memes are also used as a way to express contempt or sarcasm.

In recent years, skull memes have become popular across social media platforms, particularly on Instagram and Reddit. Some popular skull memes include the "skull trumpet" meme, which features a skeleton playing a trumpet, and the "doot doot" meme, which features a similarly styled skeleton playing a trumpet with the caption "doot doot."
