'walrussing' is a term coined originally by 'lean yellow supporting' to define a particular sexual preference by very fat and ugly old men for very young girls. In the meantime though we decided to broaden the term and use it in the sense of very fat people of either gender having sexual interplay or intercourse. The term 'walrussing' by the way has been picked up by the entire porn industry andis now used generally on the internet to catalogue, specify, detail, designate, particularize, individualize, nominate, denominate and christen the sameness of its boring products.
