Lekngai (LEK-ngai): Stiff-necked; cricked neck.
"Lekngai yo'." = "I have a crick in my neck."
"Munga maigo' taiguenao na un lekngai." = "Don't sleep like that or you'll get a stiff neck."
"Gof ya-ña umegga' TV, ya fihu lekngai gue'." = "He really likes to watch TV, and often has a stiff neck."
Note: In Chamorro you "are" lekngai rather than "have" lekngai. Also, instead of using lekngai as in the above examples, you can also use it to describe your neck, i.e.: Lekngai i tengho-hu (My neck is stiff).
