Using of あたまおかしい in various situation and translation


Recently, I found a [joke about CPU Cores/Threads
here](https://twitter.com/P5QPRO/status/818421589930745859). I catch attention
on the word "あたまおかしい" which in this context is probably:

> It is **crazily/insanely** fast.

Right? But I have seen many use of "Okashii" alone that means "weird". So many
questions regarding this phase follow:

  1. Can "あたまおかしい" in the above article, in any way, can it be translated to **too fast that head is dizzy/weird**? Instead of "mentally" craziness.

  2. Are "頭おかしい" and "頭がおかしい" have the same meaning and usage?

  3. I wonder if this phase can describe dizziness in your head. Like, you say this to your friend when your head feels weird or dizzy? "ああ、頭がおかしくなる。"

No, あたまおかしい means _crazy/insane/mad_ , not _dizzy_. Its basic meaning is of
course negative, but recently あたまおかしい has gained a positive sense, as seen in
this picture. You can say あたまおかしい is mostly positive when this word is used
for comedians, "crazy" YouTube video, etc.

おかしい just means _weird/strange/peculiar_ as well as _funny_. If it were not
for あたま in this picture, it would not make much sense.

> Are "頭おかしい" and "頭がおかしい" have the same meaning and usage?

As net slang, あたまおかしい is used almost like a single i-adjective. あたまがおかしい might
mean the same thing depending on the context, but I rarely see it. Since
あたまがおかしい is not an established slang term, I think it tends to be used in the
original (i.e., negative) sense.

あたまおかしい is still net slang, especially when this means something positive. A
safer replacement would be
[ヤバい](http://jisho.org/word/%E3%82%84%E3%81%B0%E3%81%84), which is a widely
known slang term that can also be both positive and negative.

People often add `(ほめ言葉)` to clarify it has a positive connotation. e.g,
"narutoさん頭おかしい（ほめ言葉）"

You should say
頭が[くらくら](http://jisho.org/word/%E3%81%8F%E3%82%89%E3%81%8F%E3%82%89)する or
頭がぐらぐらする to express dizziness. 頭がおかしくなる usually means "I'm going mad".
