It's when someone licks from the base of your nose to the tip. This occurs in a Doc Martin episode where he is dreaming about Louisa. Turns out to be a dog licking him, even though actress Caroline Catz actually did the deed on camera.
I was laying on the couch and my girlfriend snuggled up to me and totally Doc Martin'd my face!
The gangstaest newschoolers.com member to ever exsist. I bet you wish you were him. Gosh is he ever great. Hes known for his ganstaness, and his averagely good looks (though hes still a stud with the ladies.) He is theoretically a living god.
