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.
An absolutely foolproof way to keep minors from viewing content deemed "too mature" for them to watch.
Billy: "So I was trying to watch some videos for an M rated game, and I ran into an age gate, so I put in my real birthday. SOMEHOW it managed to figure out that I am 12. CURSE YOU AGE GATE!!!"
Bill: "Fucking age gate! *quick scroll* THERE! I was born on January 1, 1904. Fuck you age gate."
