Kahuna is a slang expression for breasts.
Kahuna is originally a Hawaiian word that means shaman or wizard. It transmogrified into meaning anything clever , good or big.
Experts believe that the final change in meaning to breast is down to breasts being clever, good, and big – if you are lucky.
The word Kahuna had its 15 minutes of fame in the Tarantino blockbuster “Pulp Fiction” as a fictitious Hawaiian Burger chain “The Big Kahuna”, which is rightly famous for their “Big Kahuna Burger”.
So deeply runs Tarantino’s fascination with this non-existent burger chain that it features in almost all of his films. Some experts believe that this is a profound statement about the centrality of burgers in American life – a meaty, cultural bedrock on which modern “Manifest Destiny” is built. Other experts believe a more likely explanation is the centrality of the burger in Tarantino’s cultural life. But we digress.
“Did you see those Kahunas? They’re divine!”.
