Interesting!!!
British way:
I fancy Ben Affleck

and daydream about him... like what I say at my earlier post.
American way:
I crush Ben Afflect

and daydream about him.... like what Americans alway says..
Right..... ?
I will find out from my American co-workers. I work for US army for 19 years and never heard one word "crush" until I learn something from AD forum.
