'Gezeik' means pissing, but it can also mean whining. So when somebody's whining or talking a lot (or whenever), I sometimes say I'm going to listen to my own gezeik.

One I use more often: 'leiding' means control/charge. It also means waterway (like with plumbing). So I like to say I'm going to take control: to take the 'leiding' in my hands.

Buuuuuuuuuut usually I just say I'm going to the bathroom, or I'm going to pee.
