Okay then, what is the difference between these two words: "grunt" vs "ugh"? They both refer to the same thing, but they are very different. One is a "label", a name given to a type of sound made by people (and other similar noises, such as a pig). The second is an imitation, in text, of a grunt. Thus, the second word is onomatopoia - an attempt to simulate a sound in pronounceable text.
"Meh" is essentially just a grunt. Someone can't meh, or meh at you. They say "meh", or go "meh". They can grunt, but they can't meh. Maybe in years to come, it will enter the English language and actually become a verb/noun, just like grunt (which, if you say it out loud, sounds rather like the sound it refers to). Until then it is just an imitation of a sound - onomatopoeia.
