A prick is a small pointy thing that hurts when it touches your skin.
When we talk about pricks, usually we mean something sharp or pointed that can cause pain. For example, if you get scratched by a rose thorn while gardening, the tiny cut is called a prick. If you wear tight clothes and they press against your skin, you might feel a series of small pricks from the fabric being too tight. We also use the word prick to describe something sharp or pointed in general - like a prickly hedge that's hard to walk through.
