"Stickies" Versus "Pinheads"
At the 1967 Sinn Féin Ard Fheis a motion from the Tippearary Cummain calling for the Easter Lily to be supplied with a self-adhesive backing was passed. After the 1969/70 IRA split, which led to the emergence of the Provisional IRA, the Official IRA and Official Sinn Féin kept the Easter Lily with a self-adhesive backing while the Provisional's reverted to the traditional paper and pin Easter Lily. This led to the members of the Official IRA and Official Sinn Féin being referred to pejoratively as the "Stickies". On the other hand, the Provisionals became known as the "Pinheads", a nickname which has not lasted.
