Once upon a time in a long lost Egyptian kingdom, there was a llama-corn (unicorn and llama) named Carl. This llama-corn grew bored one day and navigated to his favorite forum on his iPapyrus. He saw there was a post entitled "What sound does the car make when it hits the other car?". He checked the replies, which were all filled with *bump*. He then continued the trend, and thus the modern-day *bump* was born.
