In their satanic world it is a symbol of the horns. I don’t think Betty is using sign language.

Looks to me that Cher and Salma don't know how to make the devils horns hand signal correctly. I truly don't think Betty was all caught up in that mess. She may have been just going along to get along. There are a lot of people who do that. It doesn't mean they are actually involved in all of the evil. Besides, the hand sign, even done "correctly" is often known as the "Rock On" hand. I think intent comes into play.

IF Betty was doing the ILY sign..her palm is toward her..that is not ILY. Even with the sign of Bullshit...the same sign but fingers are pointed kinda to the ground (in the south) What Betty is doing in that pick CAN be used for bullshit👇 see second video video https://www.handspeak.com/word/search/index.php?id=9208 I love you👇 is this video😉 https://www.lingvano.com/asl/blog/i-love-you-in-sign-language/

The ASL for bullshit isn't even close. All fingers are in, almost like a fist.
