Why

[Prezident83]

Подскажите, плиз, как перевести в данном случае why.
He was gripping the steering wheel so hard his knuckles were white. He decided he was holding it that tightly because if he loosened up, WHY, one of those hands might just fly off and hit the ex-Prom Queen beside him right in the chops.

Заранее спасибо!
