A dialogue about can
That’s the bit of the can that drops down into the drink when we pull the tab.
Yeah, hopefully. Sometimes the tab just breaks off.
I know.
Anyway the opening is scored so that it pushes in easily but doesn’t detach itself.
OK, we can show that by drawing a shadow of it inside the can, like this I’ll label it scored opening.

what's the meaning of "score" or "scored opening"? I did not find interpretation online.

Answer

A 'score' or something that is has been 'scored' refers to a scratch or indentation that has been made.

In this case it means the lines traced in the can lid where the metal has been 'scored' to make it thinner. When the tab is pulled, the metal tears along the scored lines.
