Got this from one of my fav blogs. She now lives in NY and this obsevaruons came from her American Husband:
1) When he says the word "already" multiple times in one sentence ---example, " I already booked him already,sir for tomorrow, already." Already is only used when the action happens too soon before it should happen as in "He already left (Because he should not leave yet at this time).
2) When he points with his lips instead of his hands or fingers.
3) When he/she looks Asian with a Spanish last name.
4) When he says "wid" instead of "with" or "dat" instead of "that", "brader" instead of "brother,", "mader" instead of "mother," and so on.
I was guilty of such, but I successfully erased that habit of pronouncing the "th" as "d."
5)When she (particularly a Filipino woman) is terribly afraid of the sun.
6) When she uses an umbrella when she's out in the sun.
7) When he constantly offers food to everyone.

When he eats with a spoon and a fork.
9) When he says he takes a bath when he means a shower.
10) When he says "Sige" frequently when he talks with his fellow countrymen.
11) When he says "she" for "he" or "he" for "she" and so on. (Filipino pronouns do not convey any gender. Filipino pronouns are "unisex" such as Siya, or Kanya are not indicative of the person's sex.)
12) When he loves to sing karaoke (videoke).
13) When he wears a different pair of slippers for "inside" the house, and a different pair of slippers for "outside" the house.
14) When he brings lunch to work or school consisting of rice and another dish all placed in one container.
15) When he calls everybody Tito or Tita to people who are unrelated to him.
16) When his car has either a rosary hanging overt the windshield or a sticker of a Philippine flag .
17) When he says "I don't like you" when he's mad at you or upset at something you did.
18) When his middle name is his mother's maiden name.
19) When he writes each and every name from his birth certificate on every written form or document.
20)When he just smiles when you greet him with "Hi, how are you ?"
