“Hang tight” and “Hang loose” mean the same thing.
I was waiting for a Teams call to start, and it said “Hang tight, someone will let you in shortly.” OK, that’s fine, but then I thought it should actually be “tightly” since it is an adverb and is telling me how to hang. They got it right with “shortly” but not with “tight.”
Then I thought, hey, I don’t want to be tight, I should be loose. THEN I realized that that I could be loose, and it would mean the same thing.
Sooooo…hang loose. Someone will let you in shortly.
