I have come around that expression a few times and as a non-native speaker, I am unsure as to whether it is actually "correct" and if yes, how and when it would be appropriate to use it?
I know what "bonkers" means by the context of the usage examples and other occurrences that I had come around the information on Google, originating from the Oxford Dictionary. https://www.lexico.com/en/definition/bonkers
But I have a hard time comprehending the grammar of the expression, e.g. "calling x on y". Is "Calling bonkers on" a unique idiom or can the expression be generalized? E.g. could I "call awesome on this".?
