commentard 

A person posting in an online forum in a way which is stupid, for example by exposing himself or herself to disciplinary or legal action by making offensive or libeleous comments.

cummentary 

a collection of shared moments in memory exchanged via texts, memories of sweat and involuntary gasps, hands against flesh, and moans of intense climax; memories of soft easy laughter against pillows and the southward migration of goosebumps raised off smooth skin

Our cummentary led directly from texting to the bedroom; I couldn't wait for his clothes to hit the floor.

first commenter 

Usually 7-12 year olds on YouTube who think that commenting "first", "early", "notification squad" on a new video is going to make them cool and popular, when it, in fact, does the complete opposite.

First Commenter: "FIRST!!11!!!"
More Mature People: "Please shut the fuck up with your "first" crap."

Commentators curse

When a commentator of a sport or other competitive event praises a team or player and then that team/player soon after has something bad happen to them (concede points, injury etc.)

Commentator: Team A is looking really good this half, Team B just can't break their defense.
*Team B immediately breaks the line of defense and scores*
Team A fan: God damn it, why did he have to apply the commentators curse?
