When you are notorious for sucking bodybuilding
cock, trolling gyms in hopes of being noticed and looking for attention from men on bodybuilding forums.
It can also mean someone who considers themselves getting ready for a show, but is always
fat.
Example 1. Random bodybuilder finds a piece of ass at a gym or on a forum, he can say I scored me a chicagogirl aka. Erin, no matter the girls
name or location.
Example 2. A girl is
fat , eating on her treadmill and says she is prepping for the next show. You can say,
hey, look at that chicagogirl prep over there.
