A more proper adjective for the way in which English "rips off" other languages would be aggressively, rather than shamelessly.
"The problem with defending the purity of the English language is that English is about as pure as a cribhouse whore. We don't just borrow words; on occasion, English has pursued other languages down alleyways to beat them unconscious and rifle their pockets for new vocabulary." - http://en.wikiquote.org/wiki/James_Nicoll
