IB4TL is an acronym meaning "In Before The Lock." It's a 'game', of sorts, that people play in Internet discussion groups.

You will see this acronym used on web boards, blogs, forums, et cetera. Using it sparingly is a good strategy for boosting your post count. When you KNOW a discussion is about to be locked, you can throw a quick 'IB4TL' reply in there, and get credited as if it were a normal post, even though it is basically a useless, one-word observation.

While this is a dishonest tactic, it is generally acceptable to most moderators and admins, and the message is left to stand, as-is, towards your overall post count. High post counts are a status symbol on many sites.

The gamble is, if the thread isn't locked, it makes YOU look like a fool - a poor judge of character. Sometimes a moderator or admin will leave a discussion open, that would otherwise be locked, just to make YOU look silly. As I said, it's a 'game'...

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.
