Vektonaut 

Vektonaut / Vektanaut may be referring to a fan of a Technical Progressive Thrash Metal band called Vektor or the founder of Vektor himself, David DiSanto as it currently is David's Facebook handle and mySpace username. Although on the band's official merch page, there is a t-shirt listed as "Vektanaut T-Shirt", which complicates things a little because it could have a deeper meaning underneath David's lyrics, it could be the main character of Vektor's 3rd album Terminal Redux, yet there isn't enough evidence to support this theory.

The most likely correct explanation of this word is that back in the day, David DiSanto made up this name as a reference to his band's name, fans and friends noticed it and started calling themselves it too.

Mark: John is a real Vektonaut! He went to all of Vektor's concerts!
Dave: Yeah, he wears their t-shirts all the time.
