Worst dare I ever done was drink this nasty substance my friends and I made during a sleepover. We mixed lemon juice with wasabi, hot sauce, ketchup, soup mix, burger seasoning, cinnamon, and basically anything that sounded gross (plus my friend was Japanese and he had all sorts of these foreign sauces and spices I never heard of), mixed them together in a Dixie cup. And the dare was to drink it. I took one sip and nearly puked my heart out on the floor. So my friend was like "Ooo what's it taste like? You have to drink the whole thing!" so I got all smart like "You do it asshole!" he takes a drop, not even a sip and tastes it then nearly pukes. Also this was at like 3 AM and I was trying not to wake anyone up, so trying to keep the sound of puking down was quite the challenge. Eventually I asked to drink it in the bathroom where I could easily use the toilet if I needed to. Took another sip then dumped the rest down the drain when they weren't looking. Got really sick after that. Worse thing I've ever done lol.
