A woman's breast. More commonly (mis)spelled dooku. Stems from a turn of the 20th century japanese slang for pillow.
A girl with big dookoos conned me into taking in her cat, but I never saw her pussy.

Mary has fine dookoos, but if she doesn't start wearing a bra they're going to hang down to her knees.
