(noun, adverb/adjective)
'b-leh

1 to greet or acknowledge, but only slightly
2 to express sentiment or mood, but only slightly

Not to be confused with blah the term bleh is generally utilized as a conversation deterrent. Oftentimes people find themselves at the mercy of a conversation they do not wish to participate in. This predicament is typically initiated by a person greeting another or by a person answering a question regarding their general state of health/well being with what might be called a conversation initiator. For example, if person A were to ask person B how he/she is doing, the answer might take the form of an unwanted 30-minute conversation. It is in situations like this, where there is pressure to acquiesce a measure of social etiquette with a response but insufficient time/desire to address the situation with the full answer as would normally be offered that we have use for this term. In definition 1 then the implied sentiment, if transcribed, would be, "I acknowledge that you still exist...that's great...good work...I'd love to take the time to greet you properly but I simply cannot at the moment." (Note: it's possible that, in fact, you would not love to take the time to greet that person properly; in any instance)

Regarding definition 2, intonation is an important variable. Again the same theme of deterring a conversation is at heart, but in the interests of satisfying social etiquette the term may be used with varying intonation to reveal some extra detail as to the person's sentiment/mood. A short descending tone might, for example, reveal anger (another reason why you should not try to have a conversation with that person), while a stretched monotone might be used to express boredom or discontent. With experience this term can come to have a variety of specific meanings when accompanied by a mastery of its applicable intonation.

An adaptation of the word meh, a kind of hybrid between Bleurgh, a sound more than a word, meaning that you are totally disgusted by something, and Meh, a word of passive, unenthusiastic attitude, also meaning whatever. bleh is like a slightly disgusted meh.
person 1: "Oh look, someone just spat their chewing gum out and stuck it under a table."
Person 2: "bleh."

Put simply the word 'bleh' is a verbal 'shrug'. It can be used for every situation that a shrug of one's shoulders can. Also it can be used to show signs of frustration, confusion, indecision and boredom. It is often used in reply to a question that you have no interest in answering or have no answer for, or in a situation where you don't know what to say so you simply 'shrug' it of by saying 'bleh'.
Question: What are your thoughts on the world's economical climate?
