Single Gay Male.
This is a man who "peacocks" his clothing to get attention of other males; likes forgies and other intimate moments with large groups of other SGM's and most likely wears a Fedora.

He does not however need to be stylish- there are undercover SGM's so always be on the look out!
He's wearing loafers, of course he's an SGM
