I thought it was "Let's Get This Merged" and commented it on my own PR once.

Well, I assume you wouldn't submit a PR if it didn't look good to you, so the acronym is appropriate...

you have no idea (1) what some people do when some external force tires to make them contribute to opensource ...

1: ok, you probably do know as most people on HN probably do know

I thought it meant "Let's Get This Merge" like it was a play on "let's get this bread". I know it stands for "Looks Good To Me" now but I still prefer my reading :)

It's an ambiguous acronym. I've used it both ways.

All the front page Google results appear to say Looks Good To Me

Urban Dictionary does have Let's Get This Merged as its second definition, but it's at a net of -121 points, whereas Looks Good To Me is at net 941, and was added 10 years earlier. That doesn't seem ambiguous to me.

First time I hear "Let's Get This Money!" is a thing.

I once briefly thought it was "Let's GoToMeeting" -- like they want to schedule a call over it.

huh, I always thought it meant "Lets greet the man"
