It’s a reference to a very old SNL sketch called “shimmer”. https://www.youtube.com/shorts/03lLPUYkpYM

It probably won’t be up very long but it’s a classic.

Borax is an example of a substance that is simultaneously used for skin care, household cleaning, as soldiering flux, and ant killer. But I guess it is a constant with variable effects. Hard to be found in local shops anymore.

I worked for awhile as a janitor in a college dorm. Not an easy job but it definitely revealed a side of humanity I might not have otherwise seen. Especially the clean out after students left for the year.

I thought that you were about to write: "as a janitor in a restaurant, the dessert topping is sometimes used as a floor polish".

floor polish as a dessert topping if they're told it'll get them high.

I think that would be called a drug, not a desert topping.

For modern day web developers there are very, very, very few things that fall into the "if you do this you should probably be escorted out of the building on the first offense" category, but "reusing a variable because it's 'not being used'" might be on that list. I can maybe see the argument in very low memory embedded systems or similar systems where I'm not even qualified to come up with examples but not in anything that regularly shows up on HN for example.
