"Big Brother" competitors are claiming their butts are being violated by Jessica Graf -- whose schtick is to approach houseguests from behind and surprise them with a deep oil check.

Paul and Kevin say if she was a man poking women, she would be in jail for sexual assault. CBS has yet to comment. #DeepOilCheck#WildBillShow
