"To go mustang." To rebel, subvert, lose control of oneself.
"There's no food, no water, AMEE's gone mustang...and oh, we can breathe the air here." --Gallagher (played by Val Kilmer), describing the situation on Mars after crash-landing. AMEE is an advanced robotic instrument whose acronym stands for Autonomous Mapping Exploration and Evasion. Upon landing and discussing whether to harvest parts from Amee, she "misunderstands" their intent and switches to evasion and auto-defense mode (and "goes mustang").
