Common camera framing
Description: Both partners lie on their sides face to face and interlace the legs alternately, so each thigh sits between the other's. The weave holds the pelvises together without either partner bracing, which is what separates it from the simpler crossed-thigh positions.
Variations: A full alternating weave or a single leg through; the top arm under the head, or wrapped over the partner's shoulder to close the distance.
On camera: The interlaced legs read clearly from overhead and badly from anywhere else, which is why it appears more often in illustration than in video.
AI design considerations: Four legs in an alternating stack, which is the single hardest limb arrangement in the catalog to render without fusing. Draw the weave order explicitly rather than letting the limbs overlap arbitrarily.

Image to video (Grind (rocking))
pelvis rocks forward and back through a short arc, contact never breaking, camera is locked on a tripod and does not move.
Motion only. The still you condition on must already carry the position, wardrobe and scene: restating them causes drift.
Identifiers in other vocabularies
How this position is denoted elsewhere, and what each mapping discards. Full table in the crosswalk.
on_side records only that a character lies on one flank, and its wiki's see-also list runs to curled up, fetal position and spooning, so it covers non-sexual side-lying and rear-entry spooning alike; it is already the tag of the catalog's lateral-coital and pretzel entries. It discards the face-to-face orientation and the full alternating weave, each thigh between the other's, that holds the pelvises together without either partner bracing and separates this entry from the simpler crossed-thigh positions. interlocked_legs and leg_between_thighs restore the weave as a leg posture, and face-to-face the orientation.
