безразлично(if you do not give a hoot about something or someone, you do not care about them at all. I don't give a hoot about keeping the house tidy. (often + about) They don't care two hoots who wins as long as it's a good game. Islet)
наплевать, не обращать внимания(We are all suffering from the boss, but he doesn't give a hoot.Mы все страдает от начальника, а ему на это наплевать. Сomandor)
