The 21-year-old belly dancer was eliminated from the Channel 5 reality show on Friday after receiving fewer public votes to save than the two boys.
Speaking to Emma Willis on Big Brother's Bit on the Side, Tashie accused her fellow nominees of putting on an act to win the support of viewers.
"It felt hard... seeing them change when the nominations happened," the Oxford-born gymnast explained. "I was offended in a sense, but it was out of my hands. I thought the public will make their decision but that's up to them."
Referring to Aaron's attention-grabbing smooch with Tom O'Connell, she added: "I was not prepared to go and kiss a girl as Aaron kissed a guy and I bet now they'll calm down a little bit. Today they were a lot calmer."

Despite her distrust of the pair, Tashie did claim to have made a number of life-long friends during her "amazing" Big Brother stint, such as celebrity guest Pamela Anderson, who was revealed to have taped a goodbye message prior to her departure from the house on Monday.
"I think you're great," the Baywatch star told Tashie in the footage."You're so sparkly and bubbly and full of energy. You have a beautiful spirit about you.
"I wish you the best with everything. Good luck in your career, keep being confident and beautiful, and it was great to meet you."
