You’re sitting on a stool and someone cleats you in the forehead as part of an acceptance ritual. It’s for the most prestigious Spanish soccer club in the world. You got knocked off the stool, and the cleats really hurt your forehead, but you’re just glad to have been accepted.
This kanji also means receive, which is quite similar to accept. It shouldn't be too hard to remember.
After you've been accepted, they give you a small juice (じゅ) box to help you recover from the trauma of getting kicked. And you receive it with grace.
