In the case of guy and girl- she will bring in another girl and while the guy is fucking the other girl (who is eating out the friend) you high five each other

Windows 10 Effect

When someone uses a garbage operating system for so long that they get used to its crap factor and consider it good.

Guy: I'll never upgrade to Windows 11, Windows 10 is way better!
Doctor: You seem to be under the influence of the Windows 10 Effect, Windows 11 is the same shit. I'd recommend switching to Linux or macOS for a change.
