You won’t

Friend: Hey Joe, shove Yura off the cliff

Joe: Noo, I can’t!

Yura: You won’t

*Joe shoves Yura off of the cliff*
You won’t by rushman20 October 28, 2019
An expression used to challenge a person to commit an action.

Appropriate responses are as follows:
In agreement to do the action = "Who Won't?"
Not in agreement to do the action = "You right"
Absolutely not in agreement to do the action = "Are you dumb?"
To counter challenge = "YOU won't!"
When used in an overly serious manor "you won't" may be interchangeable with "You will not!"
Warning: Increased use of alcohol can and will cause excessive repetition.
Person 1: "You won't do jam and night." Person 2: "Who won't?! YOU won't!"

"YOU WON'T!"
YOU WON'T! by Nana. September 10, 2011
Whenever someone says they'll do something, someone else comes back with "You won't!" It's almost like a dare. If the person does said thing, the "You won't"-er usually comes back with something like "OK, so maybe you will."
Commonly used by the surf-bum kids who pioneered such gems of slang like "Dude" and "Sweet".
Person1: Man, every time my math teacher gives me homework, I want to pull a Columbine on her!

Person2: You won't!

(Person1 does. Person2 is arrested as an accessory.)

~OR~

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.

EBK stands for "Elite Ball Knowledge." 1 In internet slang, "ball knowledge" originally referred to a deep understanding of football/soccer or basketball, but it has evolved into a broader term for having a highly sophisticated, deep, or niche understanding of any specific topic (such as music, movies, or subcultures).
Person A: "That scene was a direct homage to an unreleased 1982 Japanese indie film."
Person B: "Wow, EBK."
