I tend to unconsciously pick up phrases from people around me. I do use the floored one and occasionally the slayed one below here.
My mom says That just floors me!(shocked me) or That just slayed me!(so funny!) and the one I hadn't payed any attention to but she and I got to talking about it recently. She says must you go round Robin Hood barn to explain?(meandering in your explanation) An expression from her youth. She is 76.
