Yours is my favourite (even though I've caught myself doing this on occasion.)

I have done this once, when I took my first sip of a thin mint milkshake. The noise I made led to several others trying this delicious milkshake and then ordering them. I regret nothing.

You mean like this?

I have a really good friend who makes yummy noises when he eats and literally dances in his seat. I find it hysterical, and I sort of picked it up from him.

Oh, god. This is the worst. I cannot stand noisy eaters.

HAHAHA! That would cause me to laugh uncontrollably, which probably wouldn't endear me to them either!
