1. Contact to the face as a result of ice sticking together then rushing, due to gravity, toward your face once you try to get the last sip of a delicious beverage.
2. The result of an avalanche of ice when trying to get a piece of ice from a cup where the ice is all stuck together.
I tried to get a cube of ice and the ice in my cup would not budge. I experienced ice smack after all of the ice hit my face when I tapped the bottom of the cup. Now I have grape drank on my shirt and ice all over my zebra rug.
