With all due respect,「person with stench cloud」refers to BUDDHA. Nonetheless, the Taoist sages held all religion in disdain, so ridiculing Siddhartha for refusing to bathe for six years and hence creating his own stench cloud that followed him about would not be entirely out of line, even by today's standards:
「The Buddha, or 'enlightened one,' was born Siddhartha Gautama. …[S]ix years, Siddhartha lived an ascetic life and partook in its practices, studying and meditating using the words of various religious teachers as his guide. He practiced his new way of life with a group of five ascetics, and his dedication to his quest was so stunning that the five ascetics became Siddhartha's followers. When answers to his questions did not appear, however, he redoubled his efforts, enduring pain, fasting nearly to starvation, and refusing water. …Whatever he tried, Siddhartha could not reach the level of satisfaction he sought, until one day when a young girl offered him a bowl of rice. As he accepted it, he suddenly realized that corporeal austerity was not the means to achieve inner liberation, and that living under harsh physical constraints was not helping him achieve spiritual release. So he had his rice, drank water and bathed in the river.」

「Following this incident, Gautama was famously seated under a pipal tree—now known as the Bodhi tree—in Bodh Gaya, India, when he vowed never to arise until he had found the truth. Kaundinya and four other companions, believing that he had abandoned his search and become undisciplined, left. After a reputed 49 days of meditation, at the age of 35, he is said to have attained Enlightenment.」

Note that after six years of not bathing, he stank. One dip in river water, then after 49 days of sitting in his own feces and urine (recall also the vow of not rising), he stank. Or, we cannot believe the stories are telling the truth—after all, during this time he was still flesh and blood human, or so the story goes.
