I hate to give the benefit of the doubt to the cracka here, but it does look like he's genuinely trying to get the attention of the mascot, and it's just unfortunate, his enunciation of dinger sounds like something else. Often when you're yelling, you tend to have faulty enunciation, which is why you can't really distinguish the D sound; it doesn't help the audio quality isn't the best either.
yeah, not enough evidence to get him on this one. It is rather convenient, but he getting off this time.
