A man who has forsaken his friends for a woman - one who would rather stay in and watch soap operas with his old lady than get up to some high jinks with his mates.
One can even be labeled a bloose for simply courting a young lady - and marriage makes you a bonafide permanent bloose.
See that Hendo got married eh?
Ah ken, whit a fuckin' bloose!
Are you gonna make it the night Rodge?
Fuckin' right; ah'm nae bloose!
