Any non-romantic touching or space-sharing for no particular reason, when no other point is made of it but to demonstrate how comfortable people are with each other in the midst of other things, as family, as friends, as lovers, whatever.
Like that bonus scene after the credits in Avengers where Hawkeye has his feet up on Widow's chair. They're both exhausted and battered and paying each other no attention at all, but you know they wouldn't allow it with anyone else.
Or pretty much every scene between the twins in "The Boondock Saints", especially when they're sitting shoulder-to-shoulder naked talking with their mom on the phone in one deleted scene. In a sense, it's hot, but the reason I adore it is because it's intimacy with nothing behind it beyond "I'm just that comfortable with you". Gaaah.
