Justin: "I shoved those meatballs into my girl's pussy and she popped them at my face."

This when you go to your Dr. or clinic to get an STD check. The gigantic elephant Q-tip they use to ram inside of your Johnson is very similar to the force and action exhibited by soldiers, pirates, and other cannoneers.

A subwoofer of exceedingly high volume and potency. The kind of thing that gets cops knocking on your doors at any time of the day and noise ordinance violation tickets if placed into your car.

Projectile weapon usually made from about six 12-ounce soda pop or beer cans with the all the tops and bottoms cut out except for one, which is placed at the bottom end, and held together by duct tape. Device is filled at one end with some type of explosive gas such as butane from a disposable lighter. An object such as a ball, a wadded up sock, or a potato or other vegetable is then loaded into the open end, and the gas is ignited by a lighter or lit cigarette. Makes a loud noise and, if properly made, can be used to shoot the projectile down a dormitory hallway or out a window. Not recommended for quiet floors. Generally frowned upon by Resident Advisors, college administrators, and university police.

A gdi superweapon developed in cnc 1. It reportedly blasted kane's temple of nod in the first war. In the 2nd war, its power increased a bit but wasn't important story wise. In the 3rd war, one blast can wipe out almost anything. and it looks pretty to see when it begins to vaporize and enemy position.
In Tiberian Sun, an ion cannon can destroy an obelisk of light in one shot. In Tiberium Wars, it can destroy the obelisk of light AND anything in a significant radius.
