Grew up in Western New York and called it the same thing ("Mumbly-peg"). Though our version was where you simply drop the knife between your feet and then move one foot inward until touches the knife, then repeat until you chicken out. Looks like Wikipedia contains a similar variation: https://en.wikipedia.org/wiki/Mumblety-peg.
Anybody noticed that you can't highlight text on this website? When I try to double click, it pops up an "! ALERT: Content is protected !!". Seems like a futile usefulness oversight, especially since if I really need to, I can:
- copy the text via eyeballs->keyboard
- copy the text from the dev console
- take a screenshot and extract the text with Google Photos or something
ctrl+Up: selects increasingly larger scopes, great for selecting the content of a string literal (either with or without the quotes) or grabbing chunks of call chain
