A foreshock is a smaller earthquake preceding a much larger earthquake. Many scientists hope to use foreshocks to predict upcoming earthquakes.
In particular, the East Pacific Rise transform faults show foreshock activity before the main seismic event. Reviews of data of past events and their foreshocks showed that they have a low number of aftershocks and high foreshock rates compared to continental strike-slip faults. (McGuire et al., 2005)
The 9.5-magnitude Great Chilean Earthquake had a 7.9-magnitude foreshock

A tremor that occurs before an Earthquake, scientifically. Or an action by someone who is prepared to deal with an idiot prior to that idiot acting on their shocking behavior.

A fore-shock is a minor earthquake preceding a major one. The trouble is, you don't know it's a fore-shock until after the major one strikes.

Its a small earthquake that precedes a larger one. After the major quake there are usually aftershocks as well

I would assume it's the shock that comes before the actual shock and way before the aftershock.
