1. To toss, throw, or heave something in the direction of someone or something else. They popped up from behind the bushes and started slinging snowballs at us. The people in the crowd slung rotten vegetables at the condemned man as he marched through the town square.

2. To give or offer something, especially money, to someone, especially as an incentive to do something. They slung a bunch of money at the famous actor to star in their crappy commercial.
