One of the more horrific items of practical jokery, basically a "liquid filled" used condom thrown at a (
soon to be former)
friend or preferably an enemy as you would a water balloon. Not Recommended if you want to remain
popular, or indeed, alive.
"Well your honour, I stabbed him 40 times as the previous
day he got me in the
face with a particularly well filled spunkbomb, covering my
skin my clothes, and possibly my soul, with foul salty seminal fluid"
