6-1'd 

A cursed score that many professional teams and FIFA players have been a victim of. Anyone who has been owned with this outcome has officially been 6-1'd. This bears the shame of a humilating defeat. Always stay away from a 6-1 at all costs or the consequences may be dire.

I 6-1'd my friend last week in FIFA...Haven't heard from or seen him since....
