A condition when a wannabe bodybuilder or muscle
man, usually under age 18, think their are lats are bigger than they actually are. The wannabes carry their arms out to the side arched downward in an exagerated
fashion pretending they have big muscules. If the lats were truly developed, this would be a normal posture. There is no physiological reason for the arms to
stick out if the lats
aren't there.
Lats - derived from latissimus dorsi. Back muscules that give males a "V" shape when well developed.
Air - meaning non-existent or invisible.
