A cocktail glass full of cum that girls typically drink at the end of blow bang or bukake porn.
Hey girl if you really want me to go through the labor of making you a mojito first you gotta show me ID, and then you've gotta make all these dudes bust in a glass and finish the entire spermino.
A man who fathers several childern with several different baby mamas and takes care of none of his offspring. The master of "hit it and quit it." His powerful sperm leaves a trail of destruction, unpaid child support, and fatherless children in its wake. Beware the sperminator... woe to unfertilized eggs in his path!
My ex is a total sperminator! he has 5 kids by 3 different women!
