Vagisium
Vagisium was discovered right after Penisium on Feburary 22, 2012. It is at its best when found in Lickstenstein. It is at it's largest when found at night on the streets of Las Vegas, Nevada. It is at it's smallest in Asia because there is no discovered Penisium there. When thoroughly mixed with Penisium, it will produce Babyisium. When Vagisium reaches about 50 years of age, it generally becomes unusable.
A mother and a father will mix Vagisium with Penisium to produce Babyisium, but if it's over used, it will become very large and it will have very little chance of produsing Babyisium.
