“Dinglish” is the loving description of the quirky “language” that emerges when Danish and English get mixed up.
There is nothing wrong with this price tag in Danish. “Ass” is a commonly used shortening of the word “assorterede” [English: mixed]. So what is offered here is a mixed selection of greeting cards @ DKR 19.95 each.
But it does look a little funny to the English-speaker… 🙂
