I think I've only seen this usage in anime and manga so not sure how common it is in real life. Sometimes に seems to be used as "and", usually (always?) with people, e.g. something like:
田中に黒田じゃないか! Well, if it isn't Tanaka and Kuroda!
Is this one of the inherent (but uncommon) meaning of に, some remnant of old grammar like が/の reversal, or something else altogether?
