A slang word for sex. Can be used both as a verb and a noun. Originally defined in the 1970s Toronto, Ontario, Canada. Used by upper class teenagers who were attempting to hide their promescuity from their overbearing parents. Has led to the recent fad of "Awkward Salmon".
Guy: I had some good salmon last night.
Guy2: I just got salmoned!
Guy 3: I'm gonna go to the bar to see if I can get some salmon.
