subzero

A MK player dude who pwns the fuck out of everyone with his ice blast and ice shower and to a lesser extent his ice replica.. And certainly not his fucking gay slide move but that doesn't matter because he pwns anyway.

I fucked Ringham up good using Subzero because I was fucking cheap but then again so was Ringham using Liu Wang his his bicyle kick bullshit.

SubZero

SubZero is a more extreem version of the word 'cool'.

As in:

MrB: It's not just cool, it's SubZero!
