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 – 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.
