Wedlock between members of different South Asian castes. However, as 'AFSM' marriages numerically far outnumber all other types put together, 'Intervarna' is synonymous with the union of a Fair Upper Caste Caucasoid Aryan female & a Black Low Caste Negroid-Australoid Shudra male ('Touchable' or 'Untouchable')

Thus an eminent sociologist observes "... about inter-caste marriages where the predominant trend points to upper caste women marrying dalit men, with inter-caste marriages the other way around being few & far between." 'Gender & Caste: Issues in Contemporary Indian Feminism ed Anupama Rao' Rekha Pappu. The Book Review {Persp Pubns} 28 (2004): 36. Scientists trace this well-documented craze for Dalit men among our Aryan women (both Hindu & Muslim) to the superior size of the Shudra Penis as compared to the Indo-Aryan Penis. Hence, Anti-Aryan movements advocate Intervarna unions to undermine Aryan masculinity: "One of the items of the programme adopted at the first conference of the SSP {Samyukta Socialist Party} 1966 read: 'Inter-Varna marriage should be deemed a qualification for Government employment.' ('India's silent revolution: the rise of the lower castes in North India' Christophe Jaffrelot. London: C Hurst & Co, 2003, p 262)

Thus, 'Reverse Intervarna Marriage' connotes wedlock between a Shudrani & an Aryan. Meanwhile, the related
term 'Intercaste' also denotes the interracial union of a Negro male & Anglo female in Dixie.
