AB blood has "A" proteins and "B" proteins on the red blood cells.
Give this person any kind of blood, and the body will not recognize anything as being foreign.
AB blood donor? perfect
B blood donor? B is not foreign to the AB blood
A blood donor? A is not foreign to the AB blood
O blood donor? O doesn't have either A or B proteins. It's almost like a zero instead of an "oh". So it doesn't have anything that is detected as foreign either.
In fact, O is universal donor because it doesn't have any proteins that will be foreign to any other type blood.

Blood type AB positive is the universal reciepient because they have both the A and B antigen. Because they have these antigens the body has no reason to attack the blood because it is the same match.

A cool project that I was given in the seventh grade will illustrate this: Take four cups and fill them with four different color liquids. A is red, B is blue, AB is purple and O is clear. If you pour liquid from one cup into another and it changes colors then the blood types can not be mixed. For example, if you pour liquid from cup A into cup B it will change colors. If you pour any of them into cup AB it will not change colors. If you pour cup O into any cup it will not change colors, etc.

For several reasons, humans produce antibodies that react with types of blood cells that are not found in their bodies. So, people with type O blood produce antibodies that will react with A or B cells. AB individuals do not produce any antibodies, so they can accept transfusions from any other blood type.
