When someone rubs toothpaste on their teeth with their finger to freshen their breath because they don't have a toothbrush or chewing gum.
Jeff: Hey does anyone have any gum?
Jean-Pierre: No sir, but I have some toothpaste in my pocket, you can use it for a French Dentist.
Jeff: Get away from me you filthy French animal.
