What a boyfriend
usually refers to his girlfriend
as, in the early part of the relationship. Usually replaced with 'bitchy', 'annoying', or 'crazy', at the very first sign a girl suddenly seems human to the guy, or disagrees with him about anything. 'Awesome' is synonymous with 'incredible', 'sweet', 'amazing', and other such terms of endearment.
"OMG! You're so awesome! You're incredible! I've never met a girl as amazing as you! I love you so much!"
