What does swipe mean?

My little brother and cousin are both 10 but they play on a 12u AAU basketball team so they try to act way older. I heard them saying "I got swipe" and "you have no swipe" etc. They won't tell me what it means and neither will google. I'm pretty sure it's a basketball term meaning they can steal the ball good but I'm not sure because one time my brother said "yeah you do have swipe, no "
