BOB
n.— «A United Airlines flight bound for Los Angeles turned back after a note reading “B-O-B” was found on a sick bag in a toilet. The captain decided the note could have meant “bomb on board.” But airline workers said the acronym was also commonly used to mean “best on board,” referring to a particularly attractive passenger.» —“Sydney plane bomb alert may have been mix-up” MoneyPlans (India) June 4, 2005.
