Hotsome is, of course, the slow roasted blend between Hot and Awsome. It was first used in describing a girl who was not only Hot beyond belief, but amazingly cool as well. Now Hotsome has a variety of uses, but you'll still sound like a cali slang reject when using it.
"So I met this chick at a concert last night, she was so hot! And she's a riot, totally awsome! Fuck, she's Hotsome!"
