O'Hara was so keen on soccer that at one point, she pressed her father to found a women's team, and professed that Glenmalure Park, the home ground of Shamrock Rovers F.C., became "like a second home". She enjoyed fighting, and trained in judo as a teenager. She later admitted that she was jealous of boys in her youth and the freedom they had, and that they could steal apples from orchards and not get into trouble.
