What do you think this emoticon means?

Undecided shouldn't be the term for that face.
This one reminds me of Roy Orbison after someone (maybe you) mentioned it.

To me it means ' mmmm, I am sure this has chocolate in it and I ordered rum and raisin. The level of service in this place is getting worse' but as a reply or comment on a post it means ' oh man,you are so full of crap you leave me no choice but to send you a PM typed entirely with my middle finger'

No no no. Clearly it means "I just farted and I hope nobody noticed"
Clearly it can be smelled. Euewwwweeee.

Okay, according to the little emoticon insert page here,
means "Undecided."
To me though it's more like that "Oh brother..." look (like when you roll your eyes to the ceiling over something foolish or ridiculous).
What do you think?
