Nexiversary 

The result of having a profile on the site www.nexopia.com for a year, and recieving plus for a week.

Many people rely on this for plus, because they cannot afford five dollars to spend on the internet

Wickedgame - I do not have five dollars to spend on the internet QQ. Ah well, I shall wait until my Nexiversary
