I love the word kuku
In Russian Kaki means crap when children speak about it,and Kuku is Cockoo and crazy,so this makes those words even funnier)))
Shouldn't fingernails be "kuku jari" since jari means finger and tangan means hand?
Jari is a digit (finger or toe). Therefore fingernail is Kuku tangan and toenail is kuku kaki.
Although it now accepts "kuku jari"!
