To tonk a girl using your penis means you stand in front of her and swinging you hips smack her in the face with your penis, which makes a "tonk" sound.

Chris wanted a sandwich and Jane was reading, so he stood over her tonking her in the face with his penis til she got irritated and gave in and made him one.
