Ok but actually what does this do?

its a lot more readable if you replace the : with any other function name

fork() {
     fork | fork &
};
fork

define a funktion called fork, which calls itself twice (call once, pipe ( "|" ) the result to the same function again which is run in a new thread in the background ( "&" )). Then call the newly defined function. The : is used to make it look more like emoji.
