Okay, I'll bite. "Pontual"? Are Google and I missing something? The top result is a Google Translate rendering of the Portuguese word "pontual" as "one-off" in English, which kind of fits your intent, I guess. However, various P->E dictionaries translate the word as punctual or sporadic. (Any Portuguese speakers who can shed some light for me on the difference between Google Translate and the dictionaries?) I didn't see any Google results (in the ones I scanned) indicating pontual had been appropriated into English. Am I just not hip to the latest slang?
