Reply Allcoholism 

Reply Allcoholism is a mental disorder that makes it difficult to refrain oneself from hitting Reply-all in an email thread causing pain and suffering to others receiving the emails.

Reply Allcoholics tend to share useless commentary that does not pertain to everyone on an email list which causes them to be hated by most of their friends and family.

There are no cures for Reply Allcoholism, but there are preventative measures one could take.
Jack: Sam is so annoying! Why can't he stop hitting reply all on our group emails and only email to the person that he's responding to?!

Jill: Don't be insensitive, he suffers from Reply Allcoholism.

reply guy 

1. A man who behaves in an overly familiar way and is always replying to the social media messages of a woman he doesn't know or is barely acquainted with.

2. An annoying man who replies to social media messages, in general - whether this annoyance is due to a perceived know-it-all attitude, excessive familiarity, banal arguments that the annoyed user doesn't feel compelled to reply to again and again, or violation of some imagined pecking order.
Mental health improves 120% when reply guys are blocked or muted

Reply Stalling 

When the recipient of your text message, instant message, etc. takes between 10 and 30 minutes to respond, and you take it upon yourself to read their message, and do what they did (take 10 to 30 minutes to respond). This makes for very long, non-engaging conversations.
I know Sarah wasn't at work, she just wasn't responding quickly, so I decided to begin reply stalling to get back at her.

Reply Girls 

Girls who reply to popular videos on Youtube just to get views.

They usually have their boobs hanging on the thumbnail to catch viewers then make a short video explaining stuff you already know. Also can be called the spam on youtube.
Random kid. "Oh I just watched nighahiga's newest video!"
*sees a reply video that has a girl with a huge rack as thumbnail*
" I wanna watch that"
30 seconds later...
"That was f**king dumb as f**k! I hate these reply girls!"

reply-vasocongestion

British slang for a scientist or technical expert, esp . when the speaker is not certain of the expert’s specific field of study. Not necessarily derogatory, but typically used by persons without a technical background. In the US, the equivalent would be “egghead”, “squint”, or “geek.”

Origin of the word is unknown. Started sometime in World War 2. Given the typical evolution of British slang, could easily have started because what these experts did was confusing or “baffling” to the common person.
According to the boffins downstairs, the murderer used a serrated blade.

Pee Calculus

When you have to pee in a movie but don’t want to miss anything, and must do the following mental equation: will the amount I have to pee cause enough discomfort to diminish my attention capacity for the remainder of the movie to an extent which is greater than the amount of the movie I would miss by making a mad dash to the restroom.
I saw Satantango last night, wonderful film but by the 5th hour I had to start doing pee calculus.
