Welcome to Programmer Humor!
This is a place where you can post jokes, memes, humor, etc. related to programming!
For sharing awful code theres also Programming Horror.
Is this a reference to something because I’d love to read it if you have a time to share.

This is one of those "modern Google/search sucks" moments because I couldn't immediately find examples of it in a programming language.
I actually used DDG and most I've seen, they're just used as arguments for functions notably in C and Python
It is used in
ksh
korn shell to see what executable responds to a command:https://superuser.com/a/351995
Edit: Oh, what a rabbit hole: Why not use "which"? What to use then?
