i don't really have one
a coward’s way of saying they can’t pick a favorite, usually when asked what they like most about something they didn’t even bother to think about
'I don't really have one', after being asked what they like about the party they didn’t even go to
'I don't really have one', when asked what they like about the game they didn’t even try
'I don't really have one', when asked what they like about the food they didn’t even taste
