Haley Kalil's well within her rights to talk about the Coke cans her ex Matt Kalil's packing in his pants, her lawyer says ... because she has erotic autonomy.
Matthew Bialick -- Haley's lawyer -- tells TMZ ... he plans to file a motion to dismiss Matt's lawsuit within three weeks of being formally served the summons or complaint, which hasn't happened yet.
Bialick says it's totally unreasonable to file a lawsuit on the basis of making someone liable for "exercising her sexual sovereignty by truthfully describing a sexual experience that left her in tears" .
