I appreciate your question, but the context provided only describes a flash mob as a "form of assembling humans" without any additional details about what makes it distinctive, how it works, or why it might matter. I cannot write an accurate 2-sentence overview based solely on that minimal information without inventing facts beyond what's given. To provide you with an accurate overview, I would need more context about flash mobs' characteristics, origins, or significance.
