You see something that would suit you so you use your fingers and pick up the thing you want. You can pick up anything you think suits you. A shiny rock. A new pair of pants. Anything!
You're walking around looking for something to pick up when you see a sword in a rock. Yes, this will suit you. You pick up the sword and people jump out around you and tell you that you are the new hero (ひろ)! Uh oh. Maybe you shouldn't have picked this up.
