Cloud commenting 

Tendency for all youtube account holders to share one common brain of deeply inadequate creativity. All comments are recycled for every clip replacing one or two words to "simulate" rather than achieve relevance.

X people .....(insert generic insult); where X= no. of thumbs down.

Yet another example of cloud commenting.

projectile commenting 

Talking so loudly (especially on a cell phone) that everyone within earshot hears. Often done by self-aggrandizing poseurs who want people to notice them.

"I asked the waiter to move us to a different table, because that show business agent wanna-be was projectile commenting about his meeting with George Clooney"

Dry commenting 

Commenting on a post without reacting to the post. Some OPs get annoyed about this, because they have nothing better to do than refresh the number of likes and loves on their post, hoping it will go up.

"Why you always dry commenting on people's posts in this group? and you never make your own memes. GTFO"
