This is a sped-up vocal exclamation of 'God dayum,' stretched into a quick, high-pitched burst that lasts under a second. The rushed delivery makes the familiar phrase sound more frantic and cartoonish than a normal reaction. It gives a listener an instant jolt of amused shock, like catching something unexpectedly impressive and blurting out the first thing that comes to mind.
