A very strong and friendly woman who sometimes drinks a little too much. You can find Jilly at your local watering hole singing karaoke and organizing reunions of long time friends. Jilly will go bowling every so often at a bowling alley, but does much better on her iPhone.
"Jilly set up an awesome reunion for the c/o '90 last month. I haven't seen so many of you for ages!"

Jilly is that one girl in your group of friends who loves to sing (and give critique to those who can't).
YOU: I'm going to sing at karaoke tonight. Want to come?
FRIEND: Sure, but I'm only coming to watch how much Jilly slays you on technique.
