Ding!

From BoardGameGeek:

Can you get rid of all your cards? That's what Ding! is all about - but to do so, you will not only have to keep a close eye on the discard pile, but also on the other players at the table because what they do, consciously or unconsciously, decides which cards you can throw away. Someone is looking at their cell phone and you have the matching card in your hand? Shout "Ding!" and discard! Can you get someone to talk about the weather because it matches one of your cards? Excellent – that's a "Ding!", too! -description from the publisher
