First, read this.
In layman's terms it means that an object "owns" another and when the "parent" dies, the associated item dies as well. For example: A car has an engine. If the car is destroyed, the engine is destroyed. As opposed to aggregation where the child object isn't destroyed. Let's say you have a school. If the school shuts down, the teachers continue to exist/be teachers.
