The most dangerous weapon ever concieved by man. Or rather, (for the most part) women. The weapon of choice for the most dangerous of ho's, the extendogina lashes out swiftly and engulfs its victim in acidic poon soup, with a vice grip equivalent to that of Optimus Prime giving you a titty-twister. First discovered in the pants of Katy.
"Watch out! The extendogina is coming! Everyone, grab a hat!"
