To get this achievement, you must be awake with the Xbox 360 controller in your hands. After 30-45 minutes of pushing inputs on your controller as reflected through the on-screen instructions, the game will take you to a place with many buildings, hookers and drug dealers. The achievement will unlock at this point.
In other words, play through the tutorial until you have open-world control of Franklin in Los Santos. I have confirmed that this achievement will unlock if you are simultaneously eating Doritos.
Unmissable. Just enjoy the game and worry about those other achievements! :)
