boy treasure 

A young, innocent-looking boy (often of prepubescent age and with a nice firm ass) that is available for exploition by obese men and Star Trek/science fiction fans (which is pretty much the same thing when you think about it!)

Two men passing a primary school might comment "my-my, there's some mighty fine looking boy treasure in there. Yes sir-e!"

Treasured boy 

For a male to like the same sex, to be gay, a "fag", a homo-sexual

If a man/boy is a treasured boy then he is homo-sexual and will used the term treasured as a way to say he's homo in secret so noone knows. This way he can openly express himself.
