In the filing, attorney Dolores Troiani slams Cosby as a narcissist who didn't realize Constand (who was in a relationship with a woman at the time of the alleged assault) is gay.
"In his narcissistic view of the world, defendant believes that plaintiff's every Tweet must be about him," Troiani wrote. "He is as perceptive in this belief as he claims to be in his interpretation of non-verbal cues from women he wants to seduce.
"As defendant admits in his deposition, despite his talent for interpreting female reactions to him, he did not realize plaintiff was gay until the police told him," she wrote.

Earlier this month, The New York Times received a copy of the deposition Cosby gave as part of Constand's lawsuit.
In it, he said: "I walk her out. She does not look angry. She does not say to me, 'Don't ever do that again.' She doesn't walk out with an attitude of a huff – because I think that I'm a pretty decent reader of people and their emotions in these romantic sexual things, whatever you want to call them."
Last week, Cosby's lawyer filed a motion asking for sanctions against Troiani, claiming that Troiani violated the confidentiality agreement with her court filings. He also claimed Constand's Tweets (including the words "Yes!" and "Sir!" after parts of the deposition were unsealed) and quotes she gave the Toronto Sun violated the terms of their agreement. Troiani contends that Constand was "ambushed" by the reporter and that Constand's Tweets were sent "during the time period that there was extensive publicity about gay marriage."
Troiani also took issue with media appearances by Cosby's new attorney, Monique Pressley, and Cosby's contention in a recent filing that he did not give women drugs or have sex with them without their consent. Cosby's lawyer wrote that Quaaludes – also known as "disco biscuits" – were commonly used by people in the '70s.
"Plaintiff sits quietly listening to descriptions fed to the media of celebrity parties and 'disco biscuits,' knowing that she never attended a celebrity party or requested to take a disco biscuit (or even heard of that term for that matter)," Troiani wrote.
"Still, defendant suggests that she, not he, has violated the terms of the release," Troiani wrote.
