Onetenitis: (pronounced wun ten eye tis) The condition all-too-obviously suffered by the office loudmouth...the one who is always on conference calls spouting impossible percentages, mixed metaphors, mispronounciations, bizarre and inaccurate versions of cliches, and sheer ignorance and who displays his half-baked, half-remembered, clearly inadequate education at the cost of his coworkers productivity, as in "oh my god, his onetenitis is sooooo bad today - he just agreed with somebody 1 million percent and five minutes ago he was insisting that cricket is exactly like baseball."

Derives its name from the way he disagrees with people - he only agrees with them 110%.
