lynxism
 
2.
This also includes the text smiley -.-
This is the archetypal nebism and the original, the other above nebisms are those which were the resulting spawn from Nebula's increased nebism activity
The -.- response is a typical response to a post that is veiwed as confusing or irrelevant, since Nebula is incredibley dense and stupid this is an extremly regular occurance
