The exact origin of blarg is unknown, though many claim to have invented the word. Many contend that it is a relatively recent addition to the vocabulary - that it has only been around, perhaps, for less than 20 years - while others are confident that its origin can be traced back to biblical times, but no proof exists for either theory.
Blarg is a nonsense word used to replace virtually any other word in the
English language. Known to replace simple greetings like hello,
melancholic resignations like oh well, as well as endearments like sweetie and profanity like mother-fucker, the exact definition is based on the situational context and the speaker's tone.
Being more flexible than other such nonsense words, blarg can also be used to replace entire sentences and even simple conversations, though those situations often depend on
facial expressions and even the use of props or hand movements to further define the word usage.
