I call my boyfriend viking because he goes totally wild sometimes, he's Danish and I met him in Sweden. When he's calm I call him wolf, when he's stupid I call him idiot and sometimes I call him panda because he has this abstract painting with a panda on but he thought the man who painted it painted him until I told him it was a panda. and rarely i call him pink bunny because he had a pink room with bunnies when I met him.
He calls me butterfly because he fell in love with me in the summer and I always wore this orange sweater in the evening which reminded him of a butterfly.
