Yea i always do like arigato or saying baka to ppl and i call my mom okaa-san =)

Rarely. ._.

Never. Only when joking to friends that also watch anime.

yea a lot i feel the grammar and way things are said are so much better i dont know why just do

No, there is no need or benefit.

Chotto Matte is the one phrase I like to say.

ah, I see. Well, I stilllearned something new. Lol. And yeah, I know what you mean about the KUN/ON readings. Most guides say it comes naturally, so when I see anew word with kanji I recognize, I try to read it. Then I check the dictionary later. Lol.

i do, but also because i am learning the language, and not just through anime/manga

I do a lot and my friends think im weird

Mhm... I'm guessing that "Kyou" arises from the 今 On-yomi "Kin" with the /n/ clipped,
and the 日 On-yomi "Jitsu" with the /u/ modifying.That's just a guess of course, since I haven't really looked into it...
Readings are usually kind of tricky until you figure out common ones, and then just remember Ateji readings.
I cannot wait until I learn how to remember all of this, but that's when I actually have free time. [sigh] That's self-study.

You'd be surprised how correct you have readings if you merely memorize at least one/two On and Kun per character.
Like I mentioned earlier, there's usually some sort of pattern with the readings, with an On/On or Kun/Kun orientation.

A great example is Japanese, actually! As you probably know, "Nihongo" is read part Ateji (phonetically).
日本語 - Ni from 日 On-yomi "Nichi" + Hon from the 本 single On-yomi "Hon" + Go from the 語 single On-yomi "Go."
Notice how they are all On-yomi? Besides the fact that one is an Ateji reading (first syllable), they follow On/On pattern. ^^

Teacher is another great one, and School is as well. Terms that are older in origin will generally have an On reading. (Since they are adapted).
"Sensei" from 先 On-yomi "Sen" and 生 On-yomi "Sei." (Doctor too).
"Gakkou" from 学 On-yomi "Gaku" and 校 On-yomi "Kou."
(Actually it's good to know that there are characters with only On-yomi, 校 is one).

i know zero Japanese but there are a few phrases i picked up while watching anime...and yes i do use them sometimes

it just accidentally comes out of me. XD
and people just go all "what?" :))))

Considering the fact that I'm taking Japanese, I speak in Japanese quite a lot haha.

rarely,
with just people who can speak Japanese too, others might get offended
specially those who don't know Japanese words.

Not usually, but sometimes they just slip out. Lol like when I was in a hurry one day, I answered a question my mom asked with "hai" she had, "wtf is wrong with you" written all over her face. Ah ~ memories..
