Lalita Gupta is Rajesh Koothrappali's childhood friend. Her only appearance was in Season 1's The Grasshopper Experiment. She went on a date with Raj, but it went terribly as a drunk Raj was obnoxious. She eventually ditched Rah for Sheldon, who thought she looked like a beautiful princess from a children story. At the end of the night, they departed (because Sheldon already had a dentist) and she was never heard from again.
ProfileLalita is someone who is in her mid-twenties and grew up in the same neighborhood as Raj. As a child, she used to bully Raj by kicking him in the groins, or "samosas" as according to Raj and calling him "untouchable". However, as adults, it turned out that their parents had arranged their marriage, the main reason being Raj's mother thought that he should be married at his age and that she and his father wanted grandchildren. As it turned out, just like Raj, she is also in America, to be a dental student at the University of Southern California. Raj detested this as he remembered clearly his experience being bullied by her, calling her pushy. She is also known as "Little Lalita", and her father plays golf alongside Raj's father.
She used to be fat as a kid but has slimmed down and became attractive as an adult. Sheldon felt that she resembled Princess Panchali from the children's story The Monkey and The Princess, which his mother read to him as a kid whenever he got sick.
