From the German Schzloggszeinfargen, when a woman violently slobbers over the penis making an almost eriely familiar sound of a pig choking on it's own blood after it's throat has been slashed. Frequently seen in action in many erotic adult films. Schloggin is also acceptable.
Gawt damn fool! Bitch was SCHLOGGING my rod so hard I thought she was gonna puke all over my junk!
