I've just remembered what goes in bash.rc to make /everything/ go through lolcat so I'm a happy puppy today
It's: exec 3>&1 > >(lolcat)
(if you need colours for things like vim or whatever, keep in mind all of that would be made gay too so you'd need aliases to stop it for those I guess)
Edit: aha! it's explained here how to make aliases to stop certain applications using it https://stackoverflow.com/questions/59891025/redirecting-all-output-to-lolcat
