A cold solder joint is where the solder does not adhere completely due to lack of heat in the components being soldered (the solder doesn't melt hot enough, hence the "cold"), and doesn't form a strong physical bond or good electrical connection.
Remember, a soldering iron is NOT used to melt the solder. It is used to heat up the components so that they will melt the solder. Using the iron to directly melt the solder will result in many cold solder joints. It is crucial that the components are hot enough to melt the solder to the proper temp.
Cold joints are EXTREMELY poor electrical conductors. A 200+ amp rated bullet connector isn't any good if a cold solder joint will only allow it to conduct 40 amps.
