「をぃ、をぃ」　is mere a character play(Joke). Of course, formally is 「おい、おい」

I dont't know the ancent Japanese grammar, but in present Japanese
there is nothing that 「を」comes to TOP of sentences ,being used only
as a Postpositional particle（助詞＝jyoshi).
*助詞（jyoshi）is no relation with 腐女子(fu jyoshi)

There is often using the expression that cannot be in BBS and speach bubbles in Manga similarly.
exmp.
　・「あ゛っ！」、　「い゛っ！」
　・「女性（じょせい）→ぢょせい」
