Secret Santa Is Nuts
The OP’s office had a Secret Santa thing going on. For those who don’t know, it’s when you give a gift to one co-worker that you randomly picked out of a hat or another sorting mechanism. Basically, you’re free to be as generous and as creative in your gift-giving as you like.
This person’s Secret Santa was a real Grinch. All they got was a bag of peanuts, which is probably the riskiest type of food you could give to anyone. Doesn’t the co-worker know that people with peanut allergies can die if they even touch a peanut?
