An action which was quite widespread in New York and possibly in other locations during the early 1990's. When someone would say something incorrect or stupid, any party who witnessed this could proclaim "Gill!", and then proceed to rub the back of the offender's neck with their hand, causing minor irritation to a red mark, depending on the severity of the given gill. One could also proclaim "Save mine", which would allow the person to administer the gill to the offender at a later point in time. It should be noted, however, that if the person committing the slip-up takes notice of their folly before anyone calls a gill on them, they can say "pause" and then could not be subjected to a gill. If someone calls gill after the initial speaker says pause, it's a gill on them. Giving gills is great but getting them isn't.
Person 1: "Yo, Iverson dropped 50 on the Sonics last nite...pause...he dropped 43."

Person 2: "Gill"

Person 1: "Chill, I already said pause. Save mine."

Person 2: "Damn."

Like the term 'killing it' but ten times worse.

To achieve this requires failing in the worst way possible.

Gilling is the act of inserting a raw small to mid sized fish into a vagina or anus with the mouth facing outwards, and having a penis penetrate the mouth for the purposes of intercourse. Often done in an attempt to increase tightness and odour quality.

If there is ejaculate remaining in the fish it is optional to use it in a fish based dish afterwards, like a chowder or stock.
