What is Nub Sucker?
1.
a word used when playing computer games (Dota, Diablo, WoW, CS, etc.) It means that you suck really bad, aka noob.
When playing dota it could also mean that you feed off noobs.
BUT MOSTLY IF SOMEONE CALLS YOU IT, IT MEANS YOU JUST PLAN SUCK.
WOW! Dude that guy is such a nub sucker!!!
