On the 17th of August, 2010 President Barack Obama was departing Seattle, Washington when an unidentified aircraft violated Air Force One's airspace. Two F-15E Strike Eagles were scrambled from the Oregon State Air National Guard. The resulting sonic boom was heard across western Washington. Many people thought the president's aircraft had been shot down, and the United States was at war. After the violating aircraft was found to be a single engine harbor-tour airplane, people nicknamed the whole incident Obooma.

Literally everyone, ever. Including the writer of this definition.
