A person of the male gender, who chooses to spend time with the opposite gender rather than his boys. He isnt doing this to get pussy and slay the girls, but he his doing it to find out the latest gossip. In other words, a Sweeney boy is just a plain fag.
Joe: Man, we had such a good time last night!

Mike: Yeah but too bad Donny was being such a Sweeney Boy, he missed out on having a great time with the boys!
