Hybrid half guard pass
Also known as Half Butterfly Pass — the canonical term used on this site.
Training background: describes the guard type
Descriptive — passing the half/butterfly hybrid
Hybrid half guard pass is a descriptive name for the half butterfly pass — naming the hybrid nature of the guard, part half guard and part butterfly.
Etymology. “Hybrid” flags the mixed structure of the position; “half guard pass” attaches the objective. The label has no specific lineage — it describes the passer’s task of dealing with a guard that borrows from two families at once.
Mechanics. The hybrid relies on the butterfly hook’s ability to elevate through the opponent’s hip mobility; defeating that hip mobility drops the hook and strips the position of its lifting power, leaving only the half-guard leg to clear.
Cross-reference. “Half butterfly hook kill” is a sibling alias. Full mechanical coverage on Half Butterfly Pass.
