Armpit Hold
The Armpit Hold is not a favorite for many, pinching sensitive areas of the skin, but it can result in some gorgeous shapes such as Teddy which utilizes the front of the armpit, or the Chopstick Split or Hercules which utilizes the back of the armpit.
Overall, once you get comfortable with the armpit hold, it can become one of your best friends in pole dancing, especially as you move into more advanced tricks with fewer points of contact.
