A Nat20 is a term people that play Dungeons and Dragons (DnD) use when they roll a 20 one a 20 sided die.

(A little story to go with this)
So one time in a dnd session my boyfriend was hosting, it was winter, around late november, in a world dominated by Krama(a made up species by my bf which are basically dragon furries) and the group, A anthropomorphic rusty spotted cat named alex, a purple and white halfwing krama named Rose, an unknown species of being named Lithi, and his brother Sphaler, and a yellow and white krama named Zenith (whos rose's adoptive father) were playing outside in the snow. My boyfriend set it so if you made a perfect snowball, it added 10 to the roll you got when rolling the 10 sided die. So i was Rose (who is soon gonna find out shes transmasculine, and gonna rename herself to Noxir, or nox for short) and i had rose make a perfect snowball, and aim it at zeniths crotch. Well i rolled a 10 on the d10, and with the snowball being perfect it became a Nat20. Yeah, it shouldve killed Zenith, but my bf made it so that didnt happen cause hes nice like that and it was funny as hell.

Frothability 

The measure of an emotional and over zealous consumer in an upwardly charging market, also known as a bull market. It's characterized by rising asset prices, increased investor confidence, and favorable growth in the markets, bro.
The frothability was evident as over-zealous consumers eagerly engaged in bidding wars, driving property prices to unsustainable levels reminiscent of previous speculative bubbles.

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.
