To end a relationship, either deliberately or through apathy (passive chish)
"I've had enough of this, let's chish"

"Why did Joanne chish me?"

"So do you think it's chish?"

"Aww man, Can't believe I'm been chished again"

"Hey, after a year with no contact she suddenly unchished"

"So is this chish?"

"Just cuz he hasn't got back to you doesn't mean he's actively chishing you, it might just be passive chish. Try calling him."
