The Dynamics of Blow Job Physics 

Have you even been getting head and the girl blowing you has looked up and asked “are you almost there yet?” all the while your thinking “you just started 5 minutes ago?” only to look at the clock and see an hour has passed?
This is not simply a matter of “time fly’s by when you’re having a good time”. There is a relatively simple mathematical explanation for this that also answers why some 20 year old girls look like they are in their 40s.

1. Firstly understand that like matter, time cannot be created or destroyed.

We can start by giving a Blow Job a scalar quantity to help mathematically differentiate a good blow job and bad blow job.

2. The Scalars are as follows; 0.1 – 1.9

0.1 being the absolute best possible blow job

3. The BJ/Time Equation: BJ*T= TAm

BJ= Blow Job scalar (as discussed above)

T= Real time passed

TAm= Time aged, male

Example: Your receive a decently good blow job at an estimated scalar quantity of 0.7 for sixty minutes

0.7*60= 42

Meaning that in sixty minutes of receiving head you have only aged 42 minutes, however as aforementioned time cannot be created or destroyed so the 18 minutes you lost in that hour are carried over to the girl blowing you.

So in sixty minutes of her blowing you she’s aged 78 minutes.

This explains why some women in their 20’s look like they’re in their 40’s ; they’ve given tonnes of amazing blow jobs over the past 20 years of her life, thus aging them significantly.
Dude 1: Dude you look wicked youthful
Dude 2: Yeah Jessica must have blown me back 2 years in this week alone
Dude 1: Aw yeah, Jessica loves giving sucking dick and it really shows. She amazing at it.
Dude 2: Yeah, its a ashame she looks like shes 84 though.
Dude 1: well i guess those are just the dynamics of blow job physics

Autism Swarm Dynamics 

Autism swarm dynamics is the act when one person, typically a young child a school, does something autistic and all his friends follow suit. This forms a “meme-like” culture over that thing, thus the idea itself moved amongst the social structure like a swarm. It spreads and burrows itself into the psyche of the human mind, thus forming a behavioural pattern which is seen to some as “autistic”.

The phrase serves as a name for everyone following random @everyone ping in discord communities, first diagnosed by StemmedAxis06#2372.
In #announcements on discord.gg/thegalacticrepublic server, admin StemmedAxis06 pinged everyone with the word "Bababoey". This was an autistic thing to do as it had 0 contextual preface in this server that was well known, as well as not being a proper announcement. However, autistic children are very similar in brain patterns to Redditors. And we (discord members) are all Redditors. The everyone bababoey meme spread to the other staff and then the group leaders in their own announcement channel. Because of great Autism Swarm Dynamics influence, the meme continues to appear in various text channels.

pod person 

A person pretending to be something they aren't, or an impostor. This is inferred because of the old alien movies where alien pods appear on earth and the "pod people" dispose of the humans and slowly reproduce the bodies, pretending to be humans.
The pod person was pretending to be my father, but I knew that he was an alien when he acted differently than my father ever would have.

A dead drop is a location used to secretly pass items between two people, without requiring them to meet.

Spies have been known to use dead drops, using various techniques to hide the items and to signal that the drop has been made. Drug dealers use this as well.

A common place is to duct tape the item to the underside of a toilet cover in a public restroom.

A signal is sometimes used as well to indicate there is something to pickup, like a pile of stones in a certain formation. After checking the drop the signal is removed.
"The dead drop is the restroom toilet at the Gulf station at the corner of Commercial Ave. and Georges Rd."

No Surprises Wedding

A "No Surprises Wedding," or NSW, is a wedding invitation designation that tells attendees that there can be no unplanned announcements, engagements, events or speeches at the wedding - all actions must be pre-approved by the couple. Anyone who performs an unapproved "surprise" will be asked to leave the wedding early.

This designation comes from Reddit, where so many stories of bad wedding behavior indicated a need to communicate expectations for the wedding behavior of attendees.
You are cordially invited to the nuptials of Brian and Tom on October 31 at noon.

Please note that this wedding is child-free (under 10) and a No Surprises Wedding (NSW). Reach out to wedding planner Sami Smith to request approvals or exceptions; please note that exceptions will be rare. Limited child care for under-10s will be available. All approvals will be noted and included in planning. Unapproved, or surprise exceptions, will result in guests being asked to leave.
