Narrative:

We were preparing to depart. After the boarding bridge had been pulled the appropriate 'all call' notification had been made by the lead flight attendant for doors to be armed-stand by for all call! I was assigned as flight attendant #5 2L inboard jumpseat. Within this time frame it was reported to the cockpit that I was having difficulty arming the 2L door in that the slide armed flap would not deploy. An attempt was made to disarm/rearm using the arming lever however it still would not engage/extend properly. Flight attendant proceeded to inform the captain and lead flight attendant of the arming issue. I announced via the public address system to 'disarm doors.' the captain came to door 2L and proceeded to manipulate the door in doing so he observed the situation looked out of the port hole window; armed the door and proceeded to open the door by lifting the door handle thus rendering 2L into open position. The door became stuck midway in the outward position. The door would not at this point rotate back after several attempts made by the captain. During his maneuvering of the door I took hold of his belt loop to provide him with more stability/safety reasons to hold him back. Moments later this is when the slide completed its engaging mechanisms thus becoming deployed. To my understanding there was no one below outside the aircraft when this happened. After the incident the captain proceeded back into the cockpit where it was understood by me that he made contact with the appropriate parties that needed to be informed of our situation. In-flight supervisor along with others unknown to me boarded the aircraft after the passengers had deplaned. Questions were asked of me by the supervisor and we had been advised of particulars which included that the appropriate reporting would follow within the appropriate time frame.
