A variation of the classic McDonald's Big Mac sandwich in which the standard hamburger patties are replaced by quarter-pounder burgers via special order.

This restores the sandwich to the original glory it enjoyed upon its introduction in 1968 before the burgers slowly shrank over decades until the present when they are dwarfed by White Castle patties.

Because the flimsy sesame seed buns haven't had a real burger placed on them in decades, the Fat Mac special order violates the use-as-directed warranty and may result in injury or Special Sauce spillage. For this reason it is customary to cut the sandwich into quarters and treat each fourth as if it were a dainty canape.

The Super-Size Fat Mac Value Meal is traditionally eaten in celebration of the breaking of one's diet.

Customer: "Oh yes."

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.

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.
