Quantum Wibbly Wobbly is a hypothetical particle that defies the laws of physics and logic. It has been observed to exist in two places at once, but not really. When asked to choose between two options, it will randomly select both and then complain about the lack of options.
Due to its unpredictable nature, Quantum Wibbly Wobbly is still in the process of being studied by the most esteemed scientists in the field of utterly useless research. Their findings so far are inconclusive, but they're working on it.
