Anatomic euphemism

Because most Transformers fiction is aimed at kids, and most Transformers don't have organic squishy bits, the fiction has introduced a lot of anatomic euphemisms for assorted bits of human anatomy, especially the one you sit on. Most are real mechanical or electronic terms, and also presumably real parts of Transformer anatomy. A few are also the names of Transformers. Presumably, this is akin to being named Dick Clark or Alfred Butts.
