I'm trying to find the right word to use in a (serious) comic I'm writing.
The character is an eighteen year old American girl, talking to some older women who she's just met. Suddenly, in mid-sentence, she sees someone entering the room who surprises and scares her. What does she SAY?
At the moment I've got her saying "Yikes!" But this doesn't sound to me like something any modern teenager would actually say, outside an episode of Scooby Doo. "Eek!" sounds equally implausible. Does anyone have any suggestion of a suitable interjection? I want her to stop short of actually screaming.
