mar

Added to the end of a sentence instead of "not". Basically makes the sentence prior to 'mar' mean the opposite.
Person A: poor joke
Person B: lol mar

denotes that Person B does not in fact find the joke humorous

"I like your haircut mar"
This person does not like the haircut. In fact, they probably think it is ridiculous. 'mar' is used instead of 'not' as it is much less commonly known.
