How to Sign "Dr Pepper"
To sign 'Dr. Pepper', begin with the standard sign for 'Doctor'. Hold your non-dominant hand out with the palm facing up, and tap the fingertips of your dominant bent 'M' handshape against your non-dominant wrist. Next, drop your non-dominant hand and use your dominant hand to smoothly fingerspell the letters 'P' and 'R'. This combines the sign for 'Doctor' with the abbreviation 'P-R' to represent the popular soda.
