Nope, I'm pretty sure that's just any meter based on a dotted beat. (6/8 is a compound meter because you can feel it in 2 with a dotted quarter as the main beat.) And slip jigs play with the fact that you can "slip" between a feeling of 2 (dotted quarter, dotted quarter) and a feeling of 3 (quarter, quarter, quarter) by changing where the accents fall naturally in the measure, but without changing the 6/8 time signature. (Yay fiddle music!) But that's not what I'm doing in this piece. (:
