Arnback 

Strength, Wicked and overall dangerous.

But!! It doesn't mean that an ''Arnback'' is heartless, there are some Arnback's who are made to care for people but also some to hurt others for the better good.

You are completely ''Arnback''

Armback 

An armback is when a kook surfer thinks they are doing a trick, but in reality they are just moving their arms behind them.

Taylor: "Dude, did you see me do that fatty cutback?!?!"
Johnny: "Shut up fag, that was an armback. You suck at surfing "
