A person, riding in the same golf cart as you, who shares a common interest and participates in achieving a common goal on the golf course.
JT asked Wayne "Do you want to be cartner's at the golf course on Sunday?" Wayne replied "No, Brett and I are going to ride together, so we can drink all your Double Cross and act like children."

Get the Cartnermug. This is the person you always choose to ride with when you play golf. ie. Golf tournaments when you have a team of 4 or 6 people, you always know who you will ride or drive with when your "cartner" is in the group. The honor of the title "cartner" is a level above that of a golf partner! Your "Cartner" also knows your handicap, what you like to drink while playing and never lets you leave your wedge on the green.
