Confused about the meaning of these nicknames


I was reading manga the other day and came across these nicknames that I can't
make sense of.

The context is as follows: Some mischievous students in a certain high school
are bragging about their past. It's a contest to see who is the baddest of the
bunch. But one of these students is diligent, and so, they are picking on him.

> 三中の 病院送ら
>
> 二中の 火の玉

As I understand it, this is describing someone who sends people to the
hospital, but I have no idea what the `三中の` is referring to. The same goes for
the second one.

Some other nicks that I have trouble understanding are

> 不戦勝のマサ
>
> ツ力イツパ




「[三中]{さんちゅう}」 is a nickname for a junior high school that is officially named
「〇〇第三中学校」. The 〇〇 part is usually a town or area name. Many public schools in
Japan are named using **_ordinal numbers_** like that.

So, it is like saying "(area name) 3rd Junior High School"

**_NOTE_** : Contrary to what has been stated by another user in his/her
answer, 「三中」 has nothing to do with 「中三」. The latter means "the third year in
junior high school".

Moving on...

「[不戦勝]{ふせんしょう}」means "a win by default". 「マサ」 is a common nickname for guys
whose full given names include 「まさ」.

不戦勝のマサ must be so strong that he never actually gets to fight because the
other guys always run away at the sight of him. However you translate that is
up to you as long as you know what it means. The 「の」 here is appositional.

Lastly, 「ツ力イツパ」...

The second 「ツ」 would have to be the small 「ッ」. It would make no sense
otherwise.

「ツカイッパ」 is short for 「つかいっぱしり」(使いっぱしり) , which means " **gofer** ".

In real life, it is shortened to 「パシリ」 much more often.
