WHAT ARE THE HAPS MY FRIENDS
It looks like the more common version of the idiom is “What’s the haps?” ‘What’s happenin’?, What’s goin’ on?”, which some think was popularized when Gary Busey asked the question in the Mixed Martial Arts movie Beyond the Ring (2008), though of course it had been around for some hard-to-determine time before that (associated in many people’s minds with the speech of the young and African Americans, especially men in both cases). In any case, it’s vernacular talk.
North has altered the idiom to treat haps as syntactically (as well as morphologically) plural: “What are the haps?”
Two further, typographical, features of the heading above: no comma setting off the address term my friends, and no question mark at the end. Both are matters of typographical convention that reinforce other cues to structure and meaning: my friends is easily parsed as an address term (and so can be pronounced with the appropriate prosody), and the form of the sentence is clearly that of a WH question.
So North is, in effect, Omitting Needless Punctuation — though those who recommend omitting needless stuff do so only up to conventions appropriate to the context, while North is abandoning some of those conventions in favor of brevity and simplicity.
There are lots of other vernacular features in the writing on North’s website, including a section with recommendations, entitled
BIG UPS AND SHOUTS OUT
with nounings of up and shout out, the latter used by North with an internal plural rather than the external plural you’d get from treating the verb + particle combination shout out as a unit; usage varies on such examples (some discussion here).
