When someone asks you a favour to do but you don't want/like to do it, you express your "No" by saying "lick(naaku) my armpit(sanka) then i'll do it"(Telugu language). Which is basically saying "go fuck yourself".
boy1: bro, can you bring me some water when you are coming back from the kitchen.
boy2: sanka naaku(lick my armpit)
boy2: sanka naaku(lick my armpit)
