Hnnnng 

Give or take a few H's, N's, and G's; an onomatopoeia with multiple possible uses including:

1) The sound one makes when having a heart attack.

2) The sound one makes when straining -- for instance, when attempting to lift a heavy object, or when constipated.

3) The sound one makes when presented with something overpoweringly cute or moe. The full extent of its meaning is open to a wide range of interpretation, ranging from the suppression of an innocent squeal of delight to the sound of an orgasm.

HNNNNG!!!

1. Consider the possibility of being overwhelmed by moe to the extent of having certain or multiple internal organs imploding.

Hnnnnnnnnnnggggg!!! can be considered as a reaction to such incidences of moe overload.

2. Can also be consider as the sound you make when you feel indifferent or annoyed by something

OMG! Azu-Nyan moe' gallery!! I think I... hnnggg!!!!!!!

2.

The phrase "hnnng" is a form of onomatopoeia used in context when a person sees a very sexually attractive person of the other gender, or same. I personally like to think of it as the sound a young woman makes just as she feels her ovaries are going to burst from being over exposed to excessive sexual hotness. It helps to sound it out. "hnnng-ahhh" I like to add the gasp at the end for I know that's what those fine young mistresses do when they see I have walked into the club.

Girl 1: "omg look that sexy guy from school walked in!"

Girl 2 turns in dramatically slow fashion, and locks eyes with Sexy Guy.

Girl 2: "Hnnng"

Girl 1 must now proceed to fan Girl 2 as she recovers from the sexual trauma her ovaries just endured.

The feeling one gets when they see their unrequited love/crush on the street. Taken from the sound one makes when experiencing the feeling.

"I say, old chap, is that a whale riding a bicycle?"
"Why, yes it is."

"I believe it is HNNNNG."
