Ashley: Henning asked if you wanted to hang out with us after the lectures?
Tian: Sure. It is just the three of us or did he invite those friends from his high school again?
Ashley: Of course he did, he’s such a social glue...

social glue 

A term to describe a person, mostly an extravert, who bonds together a group of people. This person is friends with everyone in the group individually, and without them the group falls apart.
Maybe the group has another thing in common (e.g. a hobby), but if it wasn't for this person they wouldn't be friends. The social glue of a group proposes activities to do, is the king/queen of the group chat, and everything the group does is awkward until the social glue arrives.

Cindy is such a social glue, if it weren't for her these friends would have never met up.

I'm shy, but thankfully my social glue friend has introduced me to some new people.
