(gew) The intensity of a moment. People outside of said event can't hear the goo.

The actual goo may not sound like goo but is best sounded out as goo. Goo's loudness depends on how intense the moment is.

I kicked dads gun, thinking it was empty. The golden hollow point ricoche'd and blew his head off GOOOOOOOOOOOOOOOO!!!!!!!!
