JackNick 

An immature person who overuses the word "WIN" to describe things he likes, but most others think is boring.

Being JackNicked is when you say something and JackNick gets butthurt and puts you on the auto-moderate list.

JackNicking is having a post removed by a moderator because you hurt their tender feelings.

Lauren's post got JackNicked because the moderator doesn't like the big words she used.

jacknickulous 

A ridiculous way of saying ridiculous. Used to accentuate the utter ridiculousness of that to which you refer. During the holiday season, this may be replaced by saintnickulous.

The way Grandma Esther butters her saltines is utterly jacknickulous.

jacknackel 

A friendly term used for someone who has screwed up.

Way to go, jacknackel.

Jacknocker 

An insult for something stupid.
Or someone stupid.

Stop being such a jacknocker.
