Someone who is fairly obviously made of fail and AIDS. Also a raging homosexual.
A slang term used as an offensive title towards someone or something that may fit the above definition/s.
O.J. Simpson, although not homosexual, committed obvious vile acts and got away with them, even though no one believes he is innocent. So he has become labeled and Aidanus.
Also, anyone that would defend Britney Spears via youtube is an Aidanus and should be mocked.
