The sudden feeling of having testicles while on the internet. This usually occurs when engaged in arguments and/or starting shit via internet posts, comments, etc.
Don't be fooled, these testicles only spawn while the host has hands attached to a keyboard, touch screen, or other typing device.
They quickly shrivel and disappear when encountered in real life.

Person 2: LOL no, he's just got some net balls.
Person 1: Ah, yes. He would never say that to that person.
