Compression lock
Also known as Calf Slicer — the canonical term used on this site.
Training background: The mechanical category: any submission that loads joints through compression rather than rotation or hyperextension.
Descriptive — tissue-compression submission category
Compression lock is the descriptive category name for the calf slicer — using “compression” to flag the soft-tissue-compression mechanic that defines the submission family.
Etymology. “Compression” specifies the load mechanism; “lock” attaches the submission category. The compound is the most generic descriptor across the broader compression-lock family (calf slicer, bicep slicer, etc.).
Mechanics. The compression loads a fulcrum into soft tissue between the attacker and a joint structure — the tissue absorbs the immediate force while the joint is pressed past safe range.
Cross-reference. “Calf crush” and “calf cutter” are alternate names. Full mechanical coverage on Calf Slicer.
