Like many arts, utilising the correct chai pivit phrase in different situations takes time, patience and perseverance.
Man - Masi, Chai piVit ?
Masi - no thank you, my husband fed me chai this morning. Another time perhaps.
Example 2 - dismissing a situation.
(moments after example 1)
Mans best friend : Dude, did that line work on masi ?
Man : just let it go man, it was a proper chai pivit moment, I much rather not think about it.
