"Rasta", Iyaric is often called Dread Talk, as evidenced in the body of research by Jamaican linguistics scholar Velma Pollard. Persons without dreads are sometimes called baldheads (somewhat derisive) or lack (more respectful); however as a common Rasta refrain points out, "It's not the dread upon your head, but the love in your heart that makes you Rasta..." meaning that many Rasta faithful themselves lack dreadlocks, while some non-Rastas, wolves inna sheeps clothes, may wear dreads solely for fashion. Dreads that were induced artificially or with additives, rather than allowed to take their natural course, are known as bathroom locks. Babylon is an important Rastafari term, referring to governments and institutions that are seen as in rebellion against the will of Jah (God). The etymology of the word is rooted in the story of the Tower of Babel, which is a Biblical origin story explaining the reasons why different cultures of the world speak different languages. In it, the Babylonians were an advanced civilisation who were constructing a tall tower, with the intentions of reaching the heavens. However, God intervened by confounding their speech, so that they could no longer communicate to each other, and subsequently could no longer construct the tower. This would have been an especially important story to the early Rastas, who all came from vastly different cultures and spoke different languages. This may also have given the early Rastas a sense of pride in their own dialect of the English language, which at the time was considered to be "broken English"; it is now officially recognised as Jamaican Patois. Babylon is further used by some to mean specifically the racist European tyrants who had oppressed black people for centuries through slavery, and people of colour through the system of indentured servitude. It has gone on to also refer to corrupt members of government, or "politricksters" who continue to oppress the poor, regardless of race. Historically, the term Babylon may have been used to refer to the Roman Empire, who were pagans, and were known to scrutinise the early Christians and were also the ones who crucified Yeshua. This relation was reinforced after the 1935 Italian invasion of Ethiopia, then ruled by Rastafari's 'Living God', Haile Selassie I, and also partly because the Roman Catholic church, as an institution, was considered an opponent of Selassie I, and thus also of Rastafari. Babylon is also sometimes used by
