dunk

A dunk is when you put something into liquid, usually water, so that it's fully covered. Think of dipping a cookie into your glass of milk.

The word "dunk" has many uses beyond just being an action with liquids. When someone dunks, they often do it on purpose - like taking a big jump and slamming the ball into the hoop in basketball, which is called dunking. In this case, dunk means to throw the ball down so that it goes into the basket really hard. This is one of the coolest things you can do on the court! It's also possible for someone to dunk something else, like a candy bar into a bowl of ice cream or a marshmallow into hot chocolate.
