Ryan Hamilton's girlfriend, Jen, must still be furious with him! This guy must have had quite a laugh at her expense with this practical joke, which could have been dangerous and should definitely never be attempted at home. As soon as she started her run, the poor woman felt her buttocks burning.Ryan hadn't just used any hot sauce for his prank - he'd used a chilli extract called Satan's Blood. The name gives you an idea of just how hot it is but to give you a sense of scale - it measures 800,000 units on the Scoville scale - whilst a Jalapeno pepper is just 1000! ‘My butt's on fire,’ she complained as she ran home, obviously in great distress. In an attempt to relieve the pain, after splashing herself with water, she went so far as to even pour almond milk onto her bum. Angry with her other half, she proceeds to hurl both insults and her shoe at him before jumping in the shower. The hidden camera footage of the prank was later put online by the Youtube channel HammyTV.
