#23: Yes, you're correct.
As a pure language discussion, you're definitely right.
However, in this thread, the context and background is quite "special."
I don't want onceortwice12's skin are shown on such kind of insulting website and being laughed by Japanese people.
外国人が彫った面白い日本語(漢字)タトゥー・刺青まとめ【失敗!?】
In this kind of website, people will see tattoos with very sarcastic eyes. So do I.
Not only 馬鹿外人 but also 自発性, 夢想家 are regarded as funny by Japanese people, right?
I don't recommend 前進あるのみ on tattoo, unless its design is perfect.
Poorly hand-written Japanese letters are extremely awful, as if saying "I have a very low IQ," "My education level is very low" or something.
For example, even when みのるほどあたまのさがるいなほかな were written in the correct order, right to left, instead of left to right, it would still be awful because the handwriting is poor.
Anyway, I won't have any responsibility against the tatoo phrase. So just forget them.
