IB (Inspired By)

The acronym "IB" in social media followed by "inspired by" typically means that the person is giving credit to someone or something that has influenced or inspired them. 

For example, if someone posts a photo of a dish they cooked and writes "IB: inspired by my grandmother's recipe," it means that they were inspired by their grandmother's recipe when they made the dish.

The use of "IB" in this context is a way to acknowledge and show appreciation for the original source of inspiration. It can also be a way to share the inspiration with others, giving them a sense of where the idea came from and encouraging them to explore it further.
