I believe the correct intelligent English version is "Why are we still single?" The "Why we still single" be frum duh hood, girlfriend. A rapper, he be proud to say it. IT is like saying "Who be single?" Lawd hab mussy on dat teachuh dat tried to sho u how to speek. 'nuff said!!!
Nah, you've got this wrong, and honestly, you sound ridiculous. In the dialect to which you are likely referring, "be" is for habitual behaviors (alternatively, one could use "stay"). For a state of being, you could just omit it entirely and say "who single?" and
that would be comparable. Or, the not uncommonly seen "who is single?", which *gasp* matches Standard English.
I've got some questions for you:
Is you single? Or you married? If you single, why you single? If you married, why you married? Where ya wife, and how she feel about how you be actin on this forum? You stay rude, and apparently dialectally uninformed.
I can speak that so much better than you and wouldn't you know it, I also speak Standard English, which you have so ignorantly called "intelligent English". Which is a little bit ironic, since you failed so miserably at speaking the version of English you tried to speak. The OP may not even speak English as a native language. And here you are shaming that person by attempting and failing to use a dialect that you so obviously are not intimately familiar with. You try to mock it, but it ended up mocking you, and now you've made yourself look like a jerk.
Please go somewhere and sit down. You are making yourself look foolish.
