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'...

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.

Person B: "Wow, EBK."

Texas is categorized as a swing state in presidential elections, but has voted for Republicans more times than for Democrats in recent history. As such, as demographics change political alignments, some Democrats believe that Texas will vote blue, or Democratic, due to their Hispanic and African American voters, who often align themselves with the Democratic Party's liberal wing.

Blexas has been cited as possible in the upcoming decades, but only if Democrats continue to win the Hispanic vote in bigger margins.
Democrat 1: What is your prediction for the 2024 presidential election?
Democrat 2: Well uh, Blexas!
Democrat 1: You've been saying that since 2008 though.
