This is a hard haiku constraint because PSHAW is almost pure attitude. It is old-fashioned, theatrical, and inherently performative, so the poem has to build a speaker or scene sturdy enough to carry that kind of dismissal. Mark’s “A GREAT FOCAL perch / AVIAN SQUAD attack, run! / ASSAY fear? PSHAW” is a strong example of handling that well: the constraint words are absorbed into one filmic action scene, and PSHAW arrives as the exact tonal flourish the speaker would use. Across the set, the stronger poems make the target word serve as social denial, breezy contempt, comic bravado, puzzle-frustration, or shared swagger, which is what keeps the haiku from sounding like it is simply reaching for an antique exclamation.
