1) An individual who has the distinct physical features of a Filipino but does not incorporate the Filipino culture into one's personality.
2) It is also when someone of a different nationality does not know that a person from the Philippines is called a Filipino and tends to call them "Philipians"
"yea im filo but i cant speak tagalog"
"its cause you're not a filo, you're philipian"
"hey are you philipian?"
"what? you mean filipino?"
"oh yea sorry i thought it was philipian"
If your little one asks you "The Question", you can semi-clearly utter, "Philippian tubes" and show him/her a map of the northern-Aegean-Sea area. That way, you are giving an essentially-truthful answer, while still "keeping the conversation G-rated" --- i.e., without divulging any actual "adult-themed" info. Plus said youngster will likely become either bored or "info-overloaded" while staring at the map, and thus will forget about his/her original question.
