Is it still common to pretend to hate the girl or guy you like?

Is that stupid method still common during the school years?

Either the girl or guy likes their crush so much but has a hard time expressing themselves or don't want their classmates knowing it. So instead of being nice, they act mean or can even somewhat bully them. They think they don't make it obvious by doing that.

I've heard others have (when they were kids or in their early teen years) behaved like that with the opposite gender. They were mean and kind of a bully to their crush but secretly like or love them.
