When one has half of their head shaved and has the uncontrollable urge to wiggle their fingers fast.

Unlike what some people may believe, a half cock is the position of the hammer of a firearm when about half retracted and held by the sear so that it cannot be operated by a pull on the trigger.
Person 1: I didnt realize I had it on half cock until I tried to fire.
Person 2: You dumbass, you gotta pay attention to that shit!

When you have half of a boner. Kind of like a chub. You cannot control it. It is just there. Big and thick.

1.75 grams of crack (nominal) which is half a 'game' (3.5 grams) - or 1/8 oz. Crack is normally sold by the 'half' (1/2 gram) which is a tiny little bag of rocks. A half is also called a "$40 piece" (dollar amount may vary) which can be broken down into "$5-$20 pieces" for users who cannot afford more, but they will also pay a much higher rate per gram. A typical, drug-addicted street prostitute will smoke 3.5 grams per day for 3-5 days straight (with no sleep) until the drug, food deprivation and sleep deprivation literally drop her. This is why you see street hookers out at ALL times of the day and night - they need 'food' (more crack). The crack 'energizes' her and makes her feel so good again that she is ready to work some more, to get more crack of course. After a while she becomes insensitive to the high and some dealer/user/pimp will teach her how to inject crack with lemon juice (or vinegar to neutralize the baking soda in the crack) intervenously, to give her a baseline, then smoking will once again give her a buzz. The acid in the lemon juice will eventually burn out her veins the IV will not work any more.
