It's been used at companies I've worked at (not Google).

I had a coworker who didn't know what it meant, and somehow assumed it was "Let's Get That Money". So now I think of that every time :)

For a long time, I actually thought it means "Let's Get That Moving". Still works.

Same here, for the same reason. Apparently that's a 50 Cent track - go fig!
