We had a kid fresh outta college hire into the office where I work. His 'thing' was: "you know".
I kinda got tired of hearing it so EVERY TIME he said it, I countered with, "No, I don't know". The first time I did it, he had this quizzical look on his face but kept on with his dialogue. And I continued with my 'not knowing'. It took him a monthor so to get out of that habit. Gotta say, ya know, the kid was kinda bright, ya know. If'n he wasn't, he'da still be saying it, ya know.
One other thing he came out with in his rendition of dialogues was "go'ing". He would say something like, I was talking with him and he goes, John did this.
So I go, How did he do that?
And he goes, with a lever to move it.
And I go,,,,,,,,,
So, every time he 'went' it (past tense of goes, ya know) I'd interject, "where'd he go ?" or "where'd you go ?" You know.
So, lots of "going" and "knowing" simply went away as he matured.
Like whatever. Like who cares, like really. like so '90s. What gets me is news people who should know how to use English well, when they say stuff like "The man was electrocuted to death" Like it drives me mental.
