There are some words which become an indispensible part of your speech. What is the prime source of such words? ... Movies :)
Parents would be surprised when I would utter "Eh item, kya kar reli hai?";) or I would land up complementing someone "Chikne aaj ekdam jhakaas lag rahela hai, bole toh chaka-chak". Would step out of the house uttering "Adieus... amigos" or saying "I'll be back." Leaving? "Let's get outta here!"
Greet a friend by "Laleti Jaan" "Oye Puttar" "Ki haal hai Kakke"? Ask me who I'am ... "...Bond. James Bond." or shrug it off by "Abbe teri toh". Bidding farewell "Hasta la vista, baby."
Flirtuous as it could get "Meine tumhe pehle kahin dekha hai" yaa fir "aapki aankhon mein kho jaate hai hum". Someone tries to go overboard "Tumhe pataa hai na ki tum bilkul paagal ho" or "Tumhari akal toh thikaane pe hai na?" or a lil abusive "Pen de takke", "kharcha paani doo kya", "Tapka dalega tereko ... khallas kar dalega". The cheesiest words "Aati kya khandaala?" Or if it really wasnt intentional but still spoken, "Kaataan laga" :-P
Thinking about something pensively & someone gives a solution, "I thought so" or if I cant brood over it further then goes "Fuh-get about it!" or something very naive but still cant grasp "Bade bade deshon mein aisi choti choti baatein hoti rehti hai" :-P A grave mistake happens and I go "Ohhh Mmmmyyyyy Gggodddd...!" If I come out successful "Perfection ko improve karna mushkil hai". ;) or shud I put it this way... "I'm the king of the world!"
Trying to be motivational "Never Say Never". Dont worry son "Victory is ours!"
And finally the words uttered incessantly, completely impossible to edit them off my speech "Jhakaas...!", "Aiylaa...!" & "Oye Teri...!"
Rest is "for me to know and you to keep guessing..."
p.s. Feel free to add more to the list
