Hindi to English Other Other

I found it here, i don't know hindi to translate this sentense. i need translation of the full sentense and word by word translation of words in this sentense also (i mean the sentense Kya item hain, baap!). Mairi: My grammar book from Class IX propounded that this is a mis-pronounciation of "Mary" and was inducted into the Bengali vocabulary by the babus of the Raj.
"Meyeta ki dekhtey, mairi!" (In Mumbai lingo: "Kya item hain, baap!") is the commonest usage of the word - though other uses vary from confession (“Mairi bolchhi, ami korini” – “I swear I didn’t do it!”) to exasperation (“Jaliye marlo, mairi” – “The bugger is making my life hell!”). The first one is found more in educational institutions while the latter is reserved for Hari Sadu-like bosses!
