I think I want a dirt jumper, with the advantage of being lower it would help me out when riding I think. Will a DJ still do everything else a regular mtb will do? Being smaller and lighter will it be more easy to go up hill also?

Dirt jumpers are usually heavier than a hard tail XC bike because they have to take hard landings. They are usually sized really small for throwing them around in the air and are meant to be ridden with the seat all of the way down, which makes them horrible for riding trails - the riding position will be all wrong. Unless you plan on staying in the jump park, don't get one.

thanks bud, im still a FNG

However, if you're having trouble finding a bike small enough and happened to find a good deal on a DJ frame and put a more trail oriented fork on it, it might be a great bike for you. Or there are people like me who have a more XC geometry frame with a DJ fork, because I wanted a fork that could take jumps and 4' drops but couldn't afford to drop $800 on a "nice" fork that could take those drops. Sure, the fork isn't as smooth on small, fast, choppy trail, but it smooths things out fine and sucks up those bigger bumps and hits. Just pointing out, there are the ideal situations, and then there are situations that are fine and sometimes more reasonable to the amount that you have to spend on your hobby. If you were to build up a DJ frame with regular "trail" components, that 1lb more that the frame may weigh isn't going to ruin your MTB experience. You probably won't notice the weight. The geometry might make a difference if you're riding with other riders and the pace is on the fast side of things for you, but otherwise it probably won't limit you too much anyway. You'll still have fun. As for the seat down part, it's not like there's a rule saying you have to keep the seat down...

My bike is 38 pounds as it is... I think this new bike is going to be quite a bit less I hope.

Haha, yeah, probably a bit less as long as you're not building up a tank of a downhill bike. No need for you to worry about the weight.
