BUR #58476 is pending approval.
create implication headlock -> choke_hold

create implication scissorhold -> choke_hold
create implication triangle_choke -> choke_hold
Most posts with headlock seem to be mistagged, since the definition says this is specifically for holding someone's neck against the headlocker's torso side. headlock sex is almost all mistagged - about 90 results, and I think only 3 are "true" headlocks. Most should instead be tagged rear naked choke or sleeper hold - and I don't really understand the distinction between those two.
arm triangle choke only has 5 posts, but 3 of them seem to actually be headlocks.
scissorhold and triangle choke are still being mistagged every now and then. (Maybe this was even worse before positive examples were added to definitions recently)
Could some of these tags be renamed to something more descriptive? I would guess most people don't know what a "rear naked choke" or "sleeper hold" exactly is. It might be the most common type of choke hold on Danbooru, but those tags are probably pretty underused.
And is there any reason why these implications don't exist? The definition for choke hold says "any type of...", which suggests to me that it's an umbrella term, but it doesn't have any implications.
