If you frequently use the term "Boyo" in your posts as your signature, then that means you love cruising ghey bodybuilder forums looking for juiced-up steroid boys, or "power twinks", to hook up with.  Hence the word "boy" in "boyo".  Often synonymous with "bisexual", that is a misnomer.  A "boyosexual" is exclusively a biological male and only interested in other biological males (the aforementioned power twinks).  They also tend to hook up with trannies, but only if that tranny was born a biological male (trans woman).
