Slang for homosexual that arose after World War I, narrowly defining filipino "cabin boys" who worked as personal butlers (and sex toys) for Naval crew aboard ship and in ports of call, notoriously at Subic Bay Naval Base in Manila. Became more widespread to mean filipino homosexual boy or man during World War II and beyond. Now generally describes filipino male homosexuals excluding transvestites. See fliptransvestitehomosexual
