Male companion suitable for flirting, joking around and other stimulation but not for a bona fide romantic relationship. So named because one can freely bat him around and even get a little breathless over him, but never depend on him for actual emotional sustenance.
"He's great fun, but he's not bf material -- he's just a cat toy."
