Hypergolic refers to the proplusion system. Hypergolic propellants react when mixed together. They don't need an ignition system, and the fuel and oxidizer are often not cryogenic which makes them easier to store. They also tend to be more reliable with less points of failure and simpler design.
Some examples:
Monomethylhydrazine (fuel) + Nitrogen Tetroxide (oxidizer) -- used in the US Space Shuttle OMS and RCS system.
Unsymmetrical Dimethylhydrazine (fuel) + nitrogen tetroxide (oxidizer) -- used in Soviet and French rockets.
Aerozine 50 (fuel, it's a blend of UDMH+MMH) + nitrogen tetroxide (oxidizer) -- used in various Apollo rocket components.

What chemical that is carried in rockets to ignite the fuel called?
This is a complex thing. Some rockets use spark plugs to ignite the fuel. The second- and third-stage engines on the Saturn V moon rocket did this. Those birds used either kerosene and oxygen, or hydrogen and oxygen, as fuel, and the most efficient way to set them off was just to stick two spark plugs off an old lawn mower or something in the engine. There's another kind of rocket called a "hypergol." Hypergolic fuel combinations ignite spontaneously when mixed, and they can be kept at room temperature so they're a good thing to use if you are building a missile - since you probably aren't planning to launch missiles every day but they need to work when you do need to launch one, they put hypergolic propellants in it. There are a BUNCH of hypergolic propellants but hydrazine is very popular in the West. The problem with any of the hypergolic propellants is they're dangerous in every way they can be - flammable, corrosive, poisonous.
