Over 18 curry

I was invited to a birthday party for one of my friends and thought I should bring a present. I do not know that much about her, but she did mention that she likes very spicy food once. I found something called "Over 18 curry" (18禁カレー). It said on the back that it is too spicy for anyone under 18, old people, pregnant people, people with heart conditions, and almost everyone else too.
