When Meat Loaf sang "I would do anything for love but I won't do that", what was "that"?

@YukikoAmagi Well, I've always been curious about that since I was about 15. I've never found out the answer for sure.

@HeadGirl don't dig in on that 😰

@YukikoAmagi Why not?

@HeadGirl

@YukikoAmagi Don't be silly. It's just a song.
