Ok, seriously. You don't really give us much to go on. Have you ever trained before or are you a novice? I will assume you are just starting out. Like I said, you are not ready to 'bulk' or 'cut'. Competitive bodybuilders bulk and cut, it's not so black and white for the average guy.
How can you even think about doing either until you are proficient in the required exercises and understand the role of nutrition? That's why I say to just start exercising, you'll start to improve anyway. If you just go all out with a bulking mindset right now, the chances are you'll just get fatter and frustrated.
Increase your activity level, learn some basic free weight exercises and do some mild cardio a couple of times per week. See how you react first off. Gradually increase your calories to compensate, again see how you react. It's a learning process and everyone is different. When you have attained a respectable level of strength and have started to lose your belly and improved your body composition, then start thinkning about bulking up or whatever. It seems everyone wants results yesterday without laying some sort of foundation first.
