'Big Brother' Fans are Pissed Contestant is Ice Cream Scooping Vaginas

A "Big Brother" houseguest tried using an ice cream scooper on the genitals of several of his housemates ... and fans are crying foul.

JC Mounduix was captured on the show's online live feed attempting to place the scooper in or around the privates of some other cast members -- namely Kaycee Clark, Kaitlyn Herman and Tyler Crispen.

At one point, JC told Kaycee to open her vagina because it "feels good." He tries it on Kaitlyn too, going under a blanket and trying to get it near her ... apparently against her will. JC also tries going for Tyler, who covers himself and says "no." Later, he's seen touching Tyler's genitals.

None of the housemates complained about JC's behavior -- not on camera, anyway -- but, many fans online are calling out producers for not disciplining JC, or kicking him out of the house entirely.
