An informal portuguese word used both in Brazil and Portugal, altough it is more common in Brazil.

It is derived from the italian word "Ciao", a salute that means either "Hello" or "Goodbye". However, in Brazil and Portugal, it is rarely used as an initial greeting - instead, it is a common substitute for the word "Adeus" - "Goodbye" in Portuguese.

The word was largely spread by italian emigrants who brought their culture, including linguistic terms, to all over the world, especially to the South American countries - Colombia, Brazil, Uruguai, Bolivia, Argentina, Venezuela, etc. It is still a very common word in Brazil.

In Portugal, the word is still in usage but it's not as common as in Brazil. In fact, in the Portuguese slang, the word "Tchau" has acquired a slighty different meaning from the original, since it is often used to respond with amusement or fright to a fantastic or unexpected statement, very much similar to the english expressions "Get out of here" or "You don't say so...".
Common meaning:

- Tchau, Diana. Vemo-nos amanhã.
- Tudo bem, João. Tchau.

- Tchau, Diana. We'll see each other tomorrow.
- Allright, João. Tchau.

Slang meaning (used more often in Portugal, altough the common usage is still as a substitute for "Adeus"):

- Imagina que a tua namorada tinha lá aparecido de repente.
- Tchau! (Bate na madeira três vezes).

- Imagine that your girlfriend would have suddenly shown up there.
- Tchau (Knocks wood three times).

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.

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.

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.
