Beth Biskobing, an English teacher in Milwaukee teacher, is fed up with illiterate graffiti. Seeing “Where da bitches at?” on a police call box and a road construction sign in her neighborhood, she duct-taped red fliers to the tags.
“Your tag SHOULD read as follows: Where are the female dogs?”
. . . “The use of the verb are allows you to write a COMPLETE SENTENCE. (Without it, you have a fragment, of course – missing the predicate of the sentence. The subject is dogs.)” she wrote.
. . . Beth pointed out that the and da are not interchangeable. And at, being the preposition that it is, doesn’t belong at the end of a sentence.
