A false expression of mirth. The volume is always too loud, and the syllabic content is rigidly controlled and always the same cadence for a given person or corporate whore. Why? because it's a practiced laugh. A laugh not to exemplify humor, but a laugh calculated to ingratiate oneself to workplace superiors. If you snort during a corporate laugh you are required by your pact with the devil to kill yourself at once. So you better get a-practicing, whores!
