Entering a situation without being fully prepared.
Origin: Muskets and revolvers have a lowered, half-cocked, and full-cock position for the hammer. During loading, the weapon is brought to a half-cock. The weapon must then be brought to a full-cock to be used. Forgetting to cock the weapon leads to it being unprepared for combat.
The boxer did'nt do any research on his opponent, and went off half-cocked to fight somebody twice his size.
When someone is beaten unbelievably bad at something such as sports, video games, trivia, or arson. Abraham Lincoln had a monster cock and gave extreme discomfort when blasting someone up the ass. Hence, the term Lincoln cocked was born.
a dumb ass school where everyone wears Vineyard Vines and name brand clothes. most people act like they're cool when they just look dumb. there's the ghetto kids, "popular" kids, and the emo kids. the teachers are good teachers but they're super strict. i fucking hate the school, but whatever.
