The act of putting lighter fluid in the head of ones penis. Then as you ejaculate you light the sperm/lighter fluid as it shoots out of your penis in a glorious blast of fiery sperm hitting the target of choice.
A man having sex with his girlfriend, about to explode says," how bout a nice Jizzs jubilee?" Then she says "like the dessert?" Then the man says,"Damn straight baby!". Then he inserts the fluid lights it, and shoots fire cum all over her face, singeing her eyebrows, yet with no clean up.
