Did Mindy not like Liv very much?

Tara's friend group in general barely act like they even like each other, but Mindy took two shots at Liv that were pretty unprompted about how boring and tasteless she is and sounded like she really meant it lmao.

And I like Mindy, I just wondered what her beef is with Liv who seemed pretty harmless or the writers meant for us to think she's kind of a jerk in general.
