Big Brother Repulsion Index: Homewreckage Among the Houseguests

Whoever declared the "finger wag" -- that wave of the index finger that usually accompanies an "oh no you didn't" sentiment -- dead has never met Big Brother houseguest Rachel. She uses it each episode to scold other houseguests, uncooperative mirrors and anything that disobeys her tyrannical rule this season on CBS. Today, Movieline will borrow Rachel's annoying social cue and wave its own finger at three of last night's most repulsive players. Homewrecking aplenty after the jump.

3. Britney ("The Girl Who Is Unknowingly Contributing to Rachel's Reign")

Most Terrible Words Spoken on Camera: "I vote for Kristen"

Repulsiveness Profile: She may rip on Rachel to everyone in the house, parade around in Rachel's hair extensions and mimic Rachel's shrieky threats ("Floaters, put on your life vests this week!"), but Britney had the opportunity to strengthen her own standing in the house this week by voting Hayden off of the show. Instead, she chose to go along with the house majority and vote Kristen off -- one of the only houseguests left for her to align with. Towards the end of the episode, Rachel revealed that she is targeting Britney for her own terror alliance.

2. Rachel ("The One Who Claims to Be a Scientist but Is Officially Credited as a Cocktail Waitress")

Most Terrible Words Spoken on Camera: "Kristen, you are the definition of the word 'bitch.' [Time lapse as she continues to rage-shriek through a confessional.] Who do you think you are talking to Brendon behind my back?! Don't you ever [finger wag] try to get between me and my man again."

Repulsiveness Profile: Rachel is the reigning villain of this season's Big Brother. She has miraculously asserted herself as the alpha houseguest in spite of a four-man alliance (that she is not privy to), a merely conversant knowledge of the English language and a personal maintenance routine that involves dipping her weave into a cauldron of Julie Chen's boiling blood each week.

1. Kristen ("The One Who Cheated On Her Boyfriend With a Houseguest")

Most Terrible Words Spoken About Her on Camera: From her friend back in Philadelphia, "For her to be making out with him is shocking because Kristen does have a boyfriend back here in Philadelphia.

Repulsiveness Profile: Ragan called her the "kindest and most compassionate person in the house," but little did he know that Kristen had been two-timing her boyfriend back home. After revealing this shocking truth, a CBS camera crew traveled out to Pennsylvania to painstakingly capture the hometown boyfriend's reaction as they rolled footage of Kristen and her showmance partner Hayden trading nightvision-ed nothings while groping each other in bed. "I am so attracted to you, it is unbelievable" has never sounded more adulterous than it did last night on CBS. As cameras zoomed in to capture any stray tear on the hometown boyfriend's face, he grimaced and found the only words suitable for network television, "I feel betrayed. I feel lied to. I'm disgusted." We are with you, nameless hometown boyfriend.
