I would understand "I was throwing my lunch up" vs "I was throwing up my lunch" to be completely equivalent. I've never heard the form of words "to throw one's hands up", but it's obvious what it means. Therefore "throwing my hands up" and "throwing up my hands" make equal sense and are equally humorous. (Not that it matters, of course there's no real ambiguity here)
