crab louse, crabs

[noun]
[de schaam-luis, de schaam-lui-zen]

"Schaamluis" is composed of "schaam" (from "zich schamen") and "luis", which respectively translate to "to be ashamed" and "louse". 

The Dutch call the area in which crabs tend to nest the "schaamstreek": the pubic area, literally the shame area…

If you have crabs, your doctor will tell you: "U heeft schaamluis" (<note: in this case the singular form is used>), or "Je hebt platjes" (<plural form again>), which is more informal…

Examples:
- "Ik ben gisteren naar de dokter geweest…ik heb schaamluis…" – "Balen!" 
("I went to the doctor yesterday…I've got crabs…" – "Tough luck!")

- "Heb je het al gehoord? Frank heeft schaamluis!" – "Dat verbaast me niks met al zijn knipperlichtrelaties…" 
("Have you already heard? Frank has crabs!" – "I'm not surprised, with all his on-and-off relationships…" Lit.: "That surprises me nothing…")

- "Schaamluizen leven van menselijk bloed." 
("Crab lice feed on human blood.")
