Reaction(s) that happen both in a quite apparent fashion,
simultaneously or possibly in sequence, but because of directly, or made possible by the fact that both related actions are rooted reactions of the same initial action, yet directly
influence the outcome of 'one or another/each other.'
There were 8 friends who all hated each other; bill, jeff, jill, jim, john, joe, jack, jane, and stephanie.
Bill hated jeff and jill.

Now imagine Bill slapping jeff and jill because he hates them, Jeff and Jill slap Jim and John because they hate them, Jim and John slap
Jack and Joe because they hate them, and
Jack and Joe both slap Stephanie because they hate her.
A person may use the actions of
Jack and Joe as obsequently occuring incidents because both were caused by apparently the same intial action, and both are related to each other on the basis of outcome, influence, and direct influence between the initial action and the consequently related reaction.
