Hammer space is the place where anime girls get their weapons from (normally, as the name suggests, hammers). This term was coined probably because anime-watchers were always wondering where on earth the girls carry their huge mallets or hammers. They seem to appear out of nowhere...well, that nowhere is Hammer Space!
With an enraged look in her eyes, she reached back behind herself and pulled a giant mallet out of Hammer Space, then started to beat the perpetrator unrelentingly.
