having sex doggystyle and placing your thumbs to the sides of your head and extending your fingers like antlers. The girl (or guy) recieving is not supposed to know. If you have a witness you've joined the bull moose club.
Last night she had no idea I pulled a bull moose. Larry was secretly watching and now I'm in the bull moose club!
