The bulk update request #10371 is pending approval.
create alias toothy_grin (4571) -> grin (103502) # has blocking transitive relationships, cannot be applied through bur
create implication grin (103502) -> teeth (911005)
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.
