Dough is a common way to misspell the proper name Doug. There are two very frequent occasions that you will find this form of misspelling.
1. Hispanic population รขยย especially when ordering late night fast food at Whataburger and they have to ask you for your name to call your order when it is ready.
2. A typo on the keyboard because the letter h is right next to g so people type the word Doug, but accidentally add the h at the end. Spell check cannot pick this up because dough is still a word.
When I get my food at Whataburger and look at the order bag, it almost always says Dough.
