look up any word, like cum:
 
1.
A person, usually of an older generation, who complains on Facebook and through comments on blogs, about the youth of today being lazy and reliant on technology. This person may also make comments about past difficulties and how "easy" younger people have it.

In other words, someone who complains about youth and technology while using the same technology to beleaguer their intended target.
"My boss routinely acts as a social curmudgeon on blogs and Facebook, by posting comments about how lazy my generation is and how we 'probably don't even know how to use a pen'"
