A person (most likely just met) that is so incredibly irrelevent, that they are more than just a random, and must be defined as such.
"Who was that annoying dude who sat with us at lunch today?"
"No clue bro, that guy's a giga random."

Get the giga random mug.
An absolute random that nobody knows.
The “giga” is added as an effect to state that the person is a nobody and a big ass random.
Look at this absolute giga random trying to give me advice like who does he think he is?

I don’t talk to giga randoms, sorry.
