Gumbar 

pronounced "goom - bar".

a cross of words coming from Goon, meaning loser with no friends, and F.U.B.A.R - standing for Fucked Up Behond Affordable Repear, a world war one saying used for when something was not right, fucked up or unfair. - in this case refurring to the personalities of the individuals or group being insulted.

Used for describing people who are socially retarded or socially backwards. often have long hair, spotty and few friends, or friends with the same social standing (a group of losers).

They often use lunchtimes to play cards and don't enjoy going to clubs and their close friends are their only friends.

gambarize 

I will try harder
I will do my very best

A word created by an illustrious member of the internet sumo community.
Its a play on words of the Japanese word gambaru -gambarimasu, a succinct word best translating to "I will do my best".
Sumo Rikishi (wrestlers) when being interviewed often end with Ganbarimasu, 'I will do my best', but when translating to English the feeling in the word gambarimasu is lost, it lacks heart.
"gambarize"
sounds stronger and is a conjunction of gambarimasu and 'ize' in English, (to make more, become) eg: modernize.
Therefore gambarize means to try harder to do my best and an apt word for the tough training and rigours of sumo.

He is still young and has to gambarize.
I need to gambarize my sumo.
He himself says he will gambarize and climb back up the ranks.
I just want him to gambarize.
I'll have to endure the pain and gambarize!
Well, all I can do is gambarize the best I can.
