तू-तू मैं-मैं (too-too main-main)

noun A single fixed expression built from the intimate pronoun तू (too, 'you') repeated with मैं (main, 'I') -- it describes a petty, shouty back-and-forth quarrel, not a literal use of either pronoun.
Sense 1 : a petty quarrel; bickering with mutual shouting/blaming
noun, feminine Usually appears with होना (honaa) 'to happen/break out' or a verb like करना (karnaa) 'to do', e.g. as the subject or object of the quarrel-event rather than describing one person's action alone.
Synonyms: झगड़ा (jhagdaa), कहा-सुनी (kahaa-sunii, milder, refers more to an exchange of harsh words), खींचतान (khiinchtaan, tug-of-war/friction, broader than just verbal)
Frequency: medium
Cultural Note: This is a classic sound-symbolic/echo formation in Hindi, mimicking two people jabbing 'tu! main!' back and forth at each other -- you will hear it used affectionately about neighbors, siblings, or in-laws having a loud but not-too-serious spat. It pairs naturally with words like मामूली (maamoolii, 'petty/trivial') to downplay the seriousness of the fight being described.
Common Mistakes: 1) Learners sometimes try to translate it literally as 'you-you I-I,' but it functions as one indivisible noun for the event of quarreling, not a description of who said what. 2) It is used for the *act* of bickering itself (तू-तू मैं-मैं होना (too-too main-main honaa, 'a squabble to break out')), not as a verb on its own -- it always needs a supporting verb like होना (honaa) or करना (karnaa).
