"For every action, there is an equal and opposite reaction, plus a social media overreaction” (or “For every action, there is a social media overreaction") is a jocular saying (based on the third of Newton’s laws of motion) that has been printed on many images.

“For every action, there’s an equal and opposite reaction. Plus a social media overreaction” was posted on Twitter by Tim Siedell on January 30, 2012.

Wikipedia: Reaction (physics)
As described by the third of Newton’s laws of motion of classical mechanics, all forces occur in pairs such that if one object exerts a force on another object, then the second object exerts an equal and opposite reaction force on the first. The third law is also more generally stated as: “To every action there is always opposed an equal reaction: or the mutual actions of two bodies upon each other are always equal, and directed to contrary parts.” The attribution of which of the two forces is the action and which is the reaction is arbitrary. Either of the two can be considered the action, while the other is its associated reaction.
