chest-burster 

A baby xenomorph, shown in the entire Alien serious as well as Alien vs Predator 1 and 2. This is the 2nd stage in the xenomorph development after a human (or something of comparable size) is attacked by a face-hugger. After a short period of incubation it burst out of a hosts' chest like an evil bloody penis, then runs of somewhere to feed and grow at an unnaturally fast rate.

A chest-burster is the last thing the hosts sees before they die.

Procaine, a numbing agent related to novacaine and cocaine, used as cocaine, but much cheaper, and legal to purchase. The procaine is cooked like as if you were using cocaine to cook crack, the end result is identical to crack in look and feel and smell, but when melted and injected because procaine and not cocaine was the end user can risk, and about 75% of the time does, having a heart attack because of the ingedients in procaine. This is where the term chest busters is used.

Them stupid niggas actually re-uped with chest busters and thought they were copping crack.

Chestburster

The accident that can happen during a titjob with two overly-enthusiastic parties: when either a man thrusts too hard, or a woman pumps too hard, a tip of the man's penis may hit the woman in the chest with enough force to cause both parties great physical pain.

This usually tends to happen when both parties are young people, as young men achieve harder erections, and young women (especially ones who haven'd given birth yet) have a lower pain tolerance.

Renee: "Lucy, what's that on your chest?"
Lucy: "Well, I gave Kevin a titjob and..."
Renee: "Oooh, was it a chestburster?"
Lucy: "Yeah. A chestburster."
