Basic butterfly sweep

Basic butterfly sweep is a descriptive name for the butterfly hook sweep — “basic” marking it as the foundational sweep of butterfly guard.

Etymology. “Basic” frames it as the first sweep taught from the position; “butterfly sweep” names the action. The label is plain and lineage-neutral, distinguishing the core sweep from its many variations.

Mechanics. The sweep is hip-driven: elevating one hook while loading the opponent toward the unhooked side uses the bottom player’s hip mobility to lift and tip them, since the butterfly’s reversing power comes from the hips and hooks rather than from pulling with the arms.

Cross-reference. “Hook sweep,” “Underhook butterfly sweep,” and “Elevator sweep” are sibling aliases. Full mechanical coverage on Butterfly Hook Sweep.
