The freshest girl you will ever see. She is super adorable, charismatic, and bubbly, and quite stubborn. She is an amazing friend to have, and is extremely academically driven. She is very loyal to all her closest friends, and has a great sense of humor. She seems to be conscientious about awkward moments in her life (that are not awkward at all!) Can also be used as a verb, to be a bubbly and charismatic person who constantly worries about being awkward.
Girl 1: Did you see that amazing girl over there, cheerful and laughing with her friends?
Guy 1: Damn, she is fine. She must be an Isheeta!
Girl 1: Honey, you have such an amazing life. Everything's totally normal and exciting and positive.
Girl 2: Yeah, but everything is just so awkward!
Girl 1: Girl, don't Isheeta and stay positive about how normal your life is.
