Huggle

additional meaning: collective noun for a group of Grandmothers. Since Grandmothers are known for their their use of a cross between hugs and cuddles, already known as huggles, it makes sense for a group of grans to be a Huggle.

"I will become an official member of the Huggle in September, when my son's twins are born."
"The Huggle had to set limits on how many grandbaby pictures could be shared by each Grandma at each Huggle gathering. "
