This post covers two entirely different elements, pair spins and twist lifts (aka. twists).
Pair spins (PSp or PCoSp for combinations) are spins where the two partners are in physical contact and spin together. Pair spins are almost always combination spins and must include at least two different basic spin positions (camel, sit, upright). Partners can do different positions at the same time. Depending on the season, one pair combination spin may be required in the short program. One pair combination spin is always required in the free skate. Pair spins are leveled from B to 4 just like regular spins, and level features include variations in position, change of direction, difficult entries, etc.

The expressions on both their faces in the Kiss & Cry basically sum this performance up. Narumi Takahashi and Mervin Tran became the first pair to medal for Japan and at World championships and did so brilliantly. Sadly, they split the next year. Still crying.
