Acute Scrotal Itch (A.S.I.)
The sudden sharp, piercing itching sensation a man gets in his scrotum. Often completely debilitating, the itch must be scratched almost immediately to avoid injury.
I was in the grocery store with my wife when I got an attack of Acute Scrotal Itch (A.S.I.). The aisle was crowded so I had to duck behind my wife to get to it.
