As someone with a peanut allergy, I actually got angry reading this. I think it's time to find a new friend. Perhaps one that won't end up killing you.

Time to get even

Epinephrine stat! Hopefully you didn't go anaphylactic op. This is one of the few times I'll say it and mean it, punch that asshole in the face. Twice.

If he definitely knew you need to pick better friends

That's not even a prank, that's just a dick-head thing to do.

Your friend is an idiot, he could have killed you. I would have stopped talking to him after that.

He's probably nuts

I feel your pain, my teacher did something similar: She thought it'd be hilarious to mix m&m's with Reese's pieces... My throat almost closed completely. Hilarious right?

Hope you had your epi-pen D: Your story reminded me of when my friend's mom spiked someone's brownies with laxatives as a joke, and then she told her daughter and her friends that story while they were eating brownies fresh out of the oven. It's just cruel

Where I come from giving someone something you know they are allergic to is assault. Take your prank war one step further by having him arrested.
