You like the person, but still the person does or acts in a way, that confuses you or makes you uneasy - but still you know the person wishes you all the best.
"You ballude!" or "You're such a ballude."
And then you laugh and wait till it's your turn.
You can ballude back by being very annoying in a cute way.
A good example of that is to sing "ballude" all the time at a melody of your choice.
