Donny says that when he hasn't REALLY got anything to say, but he can't bear the thought of himself not saying SOMETHING

'1,2, cha cha'.... I think it's New Jersey for 'I can't think of anything else'

What i guess we all need to do is find a similar phrase that means nothing unless we give it a definition, and then use it whenever we want to needle someone without actually having the balls to REALLY needle them.
Mine will be "you want fries with that?'

I mean, how could ANYONE take offense at such an innocent phrase?
