The bulk update request #10371 is pending approval.
create alias toothy_grin (4553) -> grin (103415) # has blocking transitive relationships, cannot be applied through bur
create implication grin (103415) -> teeth (910169)
Reason: The wiki defines a grin as a smile wide enough to see teeth. Toothy grin, then, is a redundant tag. Also, by that definition, teeth should be visible.
