Body Modification Ezine have a Glossary. With Pictures. For example (and if you're not squeamish/at work/reading this with your kids) check out:
pocketing "an "anti-piercing": The easiest way to describe it is that pocketing is anti-piercing. In piercing, the middle of the jewelry is under the skin and the ends are exposed. In pocketing, the ends of the jewelry are under the skin, and middle is exposed. Small “pockets” hold the jewelry in place"...(they also have a whole (hole?) pocketing section here)...
saline injection "inflation of the scrotum and other bits via saline solution: Saline solution (sterile 0.9% salt water) can be used to "inflate" body parts -- most commonly, this is the scrotum since, at least in part, it is the easiest to inflate. The penis shaft and breasts (in both men and women) can also be inflated. The saline solution can take a few days to reabsorb.
Caution must be taken to ensure that both the saline and the drip tubes and needles are sterile -- if not, a potentially lifethreatening infection can easily be drawn inside the body."
