Used to refer to homosexual men whose posture forces them to pout out their chest while standing or walking with a mincing walk. The relative positions of chest and hips makes their shirts lift up - hence shirt lifter.
"Here look, his shirt rides high. He must be a shirt lifter. That explains his gayness, I bet he swings both ways".
