Narrative:

After pushing back we received taxi clearance to taxi to runway xx. Originally ground had asked us if we could do a 180 degree turn and taxi south on alpha. After determining there was not enough room to do the turn ground instructed us to taxi to runway xx via a; G; and we would back taxi down runway xy to get into position. Ground informed us that runway condition levels were 3-3-3. We began taxiing and went at a normal safe taxi speed.after turning onto taxiway G there is a kink in the taxiway. We made the first part of kink and as the captain began to turn the aircraft back to the left I noticed we were a little to the right of center line. My feet were just off the rudder pedals in a guarding position. I reached up to put my feet on the pedals and could tell the captain had already made a full deflection as the aircraft was now sliding in a 90 degree sliding turn. As the plane kept spinning it was sliding toward the grass that was to the left side of the taxiway. The ca applied thrust reverse to bring the plane to a stop. The plane never left the paved surface. Where we ended up we determined we could not safely taxi. We checked with the fas and informed them we were going to be towed; most likely; back to the gate. The ca and I determined we should just be towed back to the gate. As the ca called ops to request the tug; I made a PA letting the passengers know what was happening and we would be going back to the gate to ensure the safety of the aircraft. We were towed back to the gate without further incident.
