babble it
When something is so crazy or awesome that it stops you dead in your tracks and you yell, 'Daaaamn!'
'I was eating a sandwich and I saw a cat wearing a hat, and I yelled, 'Daaaamn!''
'I was walking to work and saw a guy dancing on a fire hydrant, and I yelled, 'Daaaamn!''
'I was doing my taxes and I saw a number that made no sense, and I yelled, 'Daaaamn!''
