adj. Using kailua as an adjecive insinuates that someone is super cool. used in the right context, it means that they surf a lot, and are too cool for anyone else. usually people that a super kailua like to skateboard, do cool stuff, and pretty much just "CRUZZZ".
people who are kailua also have their own lingo, words such as "westaycruzinkailua", or just "cruz" (meaning, to hang out, or be super kailua".
