Siamese is a term used in naming certain still lifes (and the stator of certain oscillators). It indicates that the object consists of two smaller objects sharing two or more cells. (Still lifes sharing a single live cell are not possible: any shared live cell needs to have at least 2 neighbors within one half for stability, which would put it at 4 or more neighbors when joined up.)
A simple way of siamization is uniting two protruding preblocks into a z-tetromino: examples include carrier siamese carrier, carrier siamese snake, and snake siamese snake. Several other methods are possible however, two other examples being loaf siamese barge and elevener.
