There are two kinds of charges, let’s call them positive and negative. Equal charges repel each other and opposite charges attract each other and usually stuff is neutral (equal amounts of positive and negative charge).
Now if you add, move or remove charges from something that isn’t able to revert the process (insulating material), then you create a local charge imbalance. that for example attracts or repels stuff and if something comes in close contact so that the electric field (dependent on the inverse of the distance, so the closer the stronger) is so high that air becomes conductive, you’ll have a spark discharge (a tiny lightning), between the charged object and for example your finger.
In that case you have a current of charge moving from one place to another but if you just carry a charged thing around, then it’s static, the charges aren’t moving.
