How do you get your triceps to pop out of your arm so that they look huge even from the front?

Your triceps are made up of 3 seperate muscles. The one on the outside can be hit by doing rope pressdowns and rolling your thumb out at the bottom, as well as other exercises... Some people also just have better triceps... (I am not one of those people). I can build mass pretty easily, but even when I had a 19+1/4" arm, my triceps were big but not that defined...
