Noun. From Hawaiian.
“Deep-set eyeballs, similar to those of someone who has been ill”
A more precise word than most of the others I’ve done so far, makahakahaka is a quintessentially Hawaiian word (repeated clusters, sounding almost onomatopoeic) that I can guarantee will take you about 3 attempts to say correctly!
According to this Hawaiian dictionary, the word sounds very similar to mākahakaha (with stress on the first ‘a’) which means ‘to show signs of clearing (as in rain)’ and mākāhā (with stress on every ‘a’) meaning ‘a sluice gate.’
Stress, it seems, is an important property in Hawaiian.
