noun: An unpleasant and often embarrassing phenomenon which occurs when one consumes some foodstuff containing a high contingent of salmon. Salmon breath is often mistaken for tuna breath, but has a unique and even more pungent odour which defies and overpowers even the strongest mouth washes and mints.

Guy 2: Yeah, I reckon someone ought to let him know...
