Gill is a surname found in the Sikh Punjabi community. The Gill clan is one of the largest clans in Punjab and are found all over in the three regions of Punjab, India (Majha, Malwa, and Doaba). Gill’s control many high government positions and many are very wealthy. Most converted to Sikhism during Guru Hargobind Ji’s Guruship and were known for being exceptionally brave, honest, and noble. Gill means prosperity or richness and are one of the more elite classes in Punjab. They also won’t be afraid to bash your head in if you wrong them.

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."

"Gill" as in "giving a gill" A term used around the late 80s-early 90s, possibly regional, by children as a proclamation that someone/a friend just said something incredibly stupid or incorrect, AND that they deserve to be humiliated. It was shouted as he/she simultaneously burns the back of the other person's neck with a fast horizontal rub of the hand. Similar in nature to an Indian burn.
Person 1: Yeah, well your mother is your father. (I'm paraphrasing.)
Person 2: Not funny. You deserve a gill for that. Gill!
Person 1: Ow. What the hell?
Person 3: You're 17 and still giving people gills?
Person 2: Oh, wow. I haven't remembered a gill in a long time. Hah.

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

To achieve this requires failing in the worst way possible.
