An exceptionally large water balloon full of nasty sticky semen used for humiliating someone at a party. Throw at passing cars for additional entertainment.

White sticky icky fluid that comes out the penis, jizzbomb being a huge ass load that it takes 4-5 seconds to clear..generally sticking to the wall or flying up in the air & hitting something

(v) to covertly put a wad of jizz (semen) into someone's drink

JizzBomb; A large and unexpected amount semen that is suddenly and, violently blasted towards/onto an object or person in an explosion like fashion.

The essence of a genuine Jizzbomb works like this. When you are getting busy with your bird, as you are about to cum, you pull out of her, pull your foreskin forward and shoot inside it (it helps if you are not fully hard so you have more foreskinto cover your helmet) Your foreskin with then fill out with said jizz, like a bullfrog. At this point, you spring your cock forward whilst releasing your foreskin from your fingers, this will produce the ultimate Jizzbomb all over her (face if you are lucky)

When you are very horny and start jerking off to a good porno you'll drop a jizzbomb after a while.

One part jizz, two part red bull. Its like a jager bomb but with jizz, drink until drunk.
