An escalation of a state of Domestic Violence, whereby the "open hand" of a slap is exchanged for the "closed hand" of a fist.
"So what happened?"
"She went crazy and slapped me!"
"Oh man, that's terrible!"
"And the look in her eye; Dude, I thought she was gonna Close The Hand..."
A close sitter is somebody who sits near you on a form of public transport, normally unintentionally.
if you are sitting on a bus, and no one else is on the bus, the driver stops to pickone person up and they have the entire bus to choose a seat yet they decide to pick the seat DIRECTLY behind you thus the term close sitter.
You better close your casket! (After talking back, etc.) Almost like "I brought you in this world I can take you out", as southern parents like to say.
