Leg grab clarification

BUR #23143 has been rejected.

create alias legs_grab -> leg_grab

I understood it that leg grab also applies to multiple legs being grabbed, since that is about half of the images in the tag. While legs grab isn't used a lot, this alias would make it more clear.

One of the many reasons why these should be called grabbing own leg/holding own leg (s) / grabbing another's leg/holding another's leg (s).
