Copper wire and shove it into the positive terminal

[MotoPayton]

If I were to take a copper wire and shove it into the positive terminal of an electrical outlet and then stick the other side of the copper wire into the earth, will current flow??

Of course .. and lots for a brief time till the copper wired fused or the house circuit breaker tripped

Why would you want to do such a dopey thing ?
You are setting yourself to be a darwin Award contender

if you don't do and don't even consider such actions you will " Live Long And Prosper"

Electrical outlets don't have positive terminals, only hot, neutral and ground. If you meant the hot terminal, yes, current will flow, including through you if you aren't protected.

It's called a short circut (or line-to-ground fault). Hopefully a breaker would trip somewhere, otherwise one risks starting a fire if the circuit overheats. That is a dangerous activity that we discourage.
