I've learned a new words.

I'm hooked on learning English and the use of slang words, even though I'm probably not going to use those words while I'm speaking in English as possible.

My American friends are always use slang words in conversation, but I barely could understand them and sometimes not at all.

So, I think I probably need to learn some slang words as possible. (I think instead of 'as possible' you mean to say 'probably').

One of my friends used "smart-ass" in conversation, and I found out the meaning of the smart-ass.

I know some smart-asses, and my old friend Keiko is probably a smart-ass.

She often suddenly talks to me while I am talking with another friend.

She proudly talks to me with a smile or she seriously talks to me, and she looks like a swagger woman.

I always think that I'm not saying, Keiko.
