Scene from Back to the Future 2

Not sure if anyone noticed.

In the scene where Mindy was leaving Stan and arguing with him, she drags her suitcase down the stairs and makes a comment in response to Stan saying he got her those boobs.

she says:
"you're the one who wanted me to get these (cupping her breasts as she says it)"

In a scene from back to the future two where Lorraine (Lea Thompson) was arguing with and divorcing Biff, she was also dragging her suitcase down the stairs and then said the exact same thing and made the same gesture with her hands as she was saying it.

when I first saw it. I thought.. "Hey that's from BTTF2"

You need to have watched both movies to get what I mean.
The similarities of the two scenes are clearly similar.
