1. To physically leap or jump at (someone or something). I can't believe your cat pounced at my face! All I was doing was trying to rub its belly. Sarah could barely keep herself from pouncing at her boyfriend as he got off the train from Toronto.

2. To seize or take advantage of (something, such as a chance or opportunity) with great alacrity or enthusiasm. I understand wanting to weigh your options, but I think you'd be a fool not to pounce at the job they've offered you. I saw an opening where I might score a goal, so I pounced at it and took the shot!
