Xbox 360 account games, how do I transfer a game from one account to another?

I used to use one account and once It ran out of live I decided to buy another account because I was an idiot 7th grader (I'm in 9th grade so I'm still an idiot). So, on my old account I had many games including minecraft, mw3, bo2, mw2, halo 3, a plethora of Avatar games and many Lego games. The new account I made was primarily never used except a buying of South park: The stick of truth. I have then switched to the old account and am wanting to get the south park: the stick of truth on to my old account (account I use now). Is there a way I can transfer ownership of the game from the two accounts (I have full access to both accounts) without having to buy it again and/or keep signing in and signing out to access the game? If there's a way please tell me how.
