I'll never forget the article published about 25 years ago in a very reputable journal titled something like "child-rearing effects from Ethopian lesbians".
upon further review of hobosexual it appears there is a Seattle band with this name and it is the sexual attraction to the unkempt, "tramp" as an apparent opposite to the metrosexual. There must be homosexuals out there who like to have sex with other dirty homosexuals, or it's made up, to get attention, because every homosexual I've know is a clean freak. Give it time and they'll want their own bathroom too, under a bridge.
