It's called Framed Couplets, and Gay's write-up is very good. It's a form that, in short, uses nine syllables per line, where the couplet's first syllables rhyme as do their last ones. It was one of those that seemed much easier before actually doing the writing, but aren't most of them though? Anyhow, stop on over and check out this form, write one up and link up to D'Verse, but at the very least head on over and read the great pieces composed and linked up already.

qualities buried deep
Interesting
syllabi’s slowly creep,
Sophistically
washing love with shame,
Suffocating
bliss with doubt and blame
Found
are the fragments that still conceal
Foul
thoughts protesting joy, reveal
Detaining
crutches that hold us back,
Defining
man, solely by his lacks
Variety
and selection, are
Varicose
to those afraid to start
Travails,
shielding as not to betray
Troubled
arteries alone and frayed
