I finally figured out "HOH" at Tootsies

You guys swore it was nothing when I said a bunch of girls were in a group and added "HOH" to their instagrams

They made an official page. Here it is, House of Hotties, with some of the same pictures:

It's still unclear whether this is strictly a girl gang of friends/partners or if there is some kind of boss based on how they talk about it
