The Lock And Cock is a sexual action preformed as follows. Stick the tip in and lock making it the lock portion, start jerkin' it and when you get close to finishing make a beeping noise like a lock on missile then say the words "target acquired" as you send it balls deep and let er rip and that is the cock portion of the Lock And Cock maneuver.
