The tag alias #75488 contortionism -> flexible has been rejected.

Reason: Synonyms, contortion and contortionist are already aliased.

However, I could see an argument for unaliasing contortionist and canonizing contortionist/ism an extreme version of flexible, let me know what you think.

EDIT: The tag alias contortionism -> flexible (forum #441316) has been rejected by @spe.

I like the idea of a tag for flexible and contortionism. While there is a bit of grey area between the two, looking at the tags it seems like there are few under contortionism that could be argued to be merely flexibility, and vice versa.
It seems that there is a distinct kink element to contortion that isn't captured by the flexible tag.

The bulk update request #10577 is active.

remove alias contortion (2) -> flexible (10900)
remove alias contortionist (0) -> flexible (10900)

Followup:

alias contortion -> contortionism
alias contortionist -> contortionism
imply contortionism -> flexible

Yeah, let’s go with option two. flexible has a bunch of implications that cause it to appear on posts that are nowhere near what you would expect of contortionism, like splits. Flexible yes, but not contorted.

The bulk update request #10579 is pending approval.

create alias contortion (2) -> contortionism (156)
create alias contortionist (0) -> contortionism (156)
create implication contortionism (156) -> flexible (10900)
