Guardians of the Galaxy Trailer- Sex Crime Joke?S

After seeing the amazing trailer for GotG, I must have re-watched it over 20 times now to really understand as much as possible from this trailer. And while watching them describe Quill aka Starlord. I saw that they had said under his criminal record '1 COUNT SEX CRIME -ILLEGAL MANIPULATION OF GRAMOSIAN DUCHESS' See screenshot above. I'm wondering what this could possibly mean, I was bit offended at first. Is it a joke? What does it even mean? I'm quite confused and slightly offended. Anyone else have other thoughts?
