lesson two! foodstuffs.
Point to yourself for "I". The sign for 'eat' is pretty obvious as well, just make your hand look like you're holding a chip or something, and put it near your mouth. The sign for 'dead' is like this:

Hold your arms as if you're cradling a baby, and that's the word for "baby/babies".
One of my favourite signs is the sign for milkshake. You use only one hand for it. For the word milk, you hold out your hand and open it and close it, making sqeezing motions, like you're milking a cow. For shake, you make your hand a fist and shake it up and down. The resulting compound word looks like you're jerking off :D

vagoo: use your thumbs and forefingers to make the shape of a vagina. (fingers point down, thumbs are up)
Hold your hand out next to you as if you are patting the head of a child for "little". Then you can run your thumb along your cheek for 'girls' or make a "talking" motion with your hand near the top of your head for 'boys' (the motion is as if you are grabbing the front of a baseball cap).
