This set represents symbols notorious for their high temperature which could kill a super fragile human being, or at least harm their health. The most dangerous symbol here is fire, of course, and it's also the most demanded one. But don't take hot-dogs for granted, they're here for a reason too! Although it's only about the name (hot will be hot), when cooked properly it may cause a lot of inconvenience for your stomach. Jokes aside, hot dogs could put your ass on fire. In other words, they deserve to be here.
