When a person who seems to be or acts like he's a bad ass, turns out to be a scared little cry baby girl when it's time to step up to the plate and ride a roller coaster. The said person will come up with all kinds of bullshit reasons why they can't ride, like health,back problems, or they have a headache or some other crock of shit. When the real reason is they are just great big scared babies, who are afraid of roller coasters.

Short for ultimate bias. Typically used by fangirls and fanboys to describe their favourite celebrity amongst the many that they are fans of.
