When a woman (or a man) has an addiction to shlong(s) (penis).
"I was getting my schlong sucked by some woman I just met at the public health department." "She would not let go of me until I dropped every drop of my spunk at the back of her throat." "Her four children were constantly asking their mother why they coulden't turn around and see what she was doing. She was clearly a Schlongohaulic."
