When you have had so much sex with a lady that she can no longer walk. A reference to former president Franklin Roosevelt, who had polio for most of his life and was confined to a wheel chair. This term is believed to have originated on the campus of the University of Central Florida.
"Man, did you hear me crank that Roosevelt on her last weekend? She hasn't been able to walk for 2 days".
