Aimee has #couragehasopinions. I'd casually suggest #couragestopbeinganasshole, but that's just me.
Kristen has #specialneedshorse and #furrysoulmate. It shouldn't be hard to tell which hashtag belongs to which horse. Someone is in that relationship is guilty of costing their mother a lot of money on vet bills, and it's not the blaze-faced smushy one.
And lately Bobby has adopted the #bobbyproblems hashtag. His problems are wide-ranging, from not wanting to horse to not looking like a horse.
What about you guys? Social media accounts or not, what is your horse's hashtag?
