The "it" in "you're full of it" refers to "sh*t". Means at best that the person saying it thinks that what you're saying is wrong, inaccurate or exaggerated.

All the way. Totally involved in what one is doing. Doing something as rapidly and thoroughly as possible. It's a slang term: "Man, when he won that race, he was going full tilt boogie."

For goaltenders, there is no left-hand or right-hand. They are called full right and regular. Regular catches with the left hand and full right goalies catch with the right hand.
