Crossed Thumbs Sign

[Ice]

I know a little sign language and someone asked me to find out what it means when you cross your thumbs, and have your fingers balled into fists and you use your one thumb to push both hands away from you. Thanks!

I hope it is OK for me to reply over a year later.

Do you think the sign might be PERMANENT?
