What does “aba cno yan” mean in filipino language?

This guy I like took a quiz on facebook and his result said that the name of the person he likes starts with a C (like my name).

Then one of his friends commented on it in a filipino language, I'm not sure if it was tagalog or not.

But they said "aba cno yan"

does anyone know what that means?

What is the tagalog translation of the following words:?

This is from a quiz that they pass around on email. I've answered all but the last few which are those below. In paranthesis are some of the words I already tried:

1. Alternate (not kapalit etc...)
2. Approach (not lapit)
3. calf (not binti)
4. erase (not bura)
5. gerund
6. pronoun
7. sewerage

Thanks! So far my score is 93 of 100.
Panghalip is right!
Anak ng baka didn't work though.
Bisiro is correct!!! All other answers so far misses.
Bravo TRANQUIL. Correct are:
sewerage= alkantarilya
erase= pawi
approach= dulog
