Usage of the words is not very regular in daily life but to know about them should be known if someone wants to understand cultural or language subtlety. The term also includes a specific aspect of the word called the ‘mert definition’. If you want to know what the exact ‘mert definition’ is, it can help bring some relevancy in the US. Although the ‘mert’ scanner might not be familiar to you, it is all relevant in some communities and fields. The full meaning of mert needs some context and cultural references to get better interpretation. So, my on-mert observation: Knowing the ‘mert’ definition gives one a deeper understanding of how it is used and what that use means in different contexts across America. Used both in the context of academic discourse and casual banter, familiarity with the definition adds clarity to communication equating to a better cultural understanding.
