“What do you get when you put guacamole on a BLT?”/“An LGBT.” (Gay BLT)

BLT and LGBT aren’t related terms, but there’s a joke:
 
Q: What do you get when you put guacamole on a BLT?
A: An LGBT.
 
“Would that be a gay BLT that only likes other BLT’s?” was posted on Twitter on April 28, 2009. “Is it wrong that we call a BLT with guacamole an LGBT?” was posted on Twitter on June 11, 2009.
 
         
Wikipedia: BLT
A BLT (Bacon, Lettuce, and Tomato) is a type of bacon sandwich. The standard BLT is made up of four ingredients: bacon, lettuce, tomato, and bread. The BLT evolved from the tea sandwiches served before 1900 at a similar time to the club sandwich,[citation needed] although it is unclear when the name BLT became the norm.
 
Wikipedia: LGBT
LGBT, or GLBT, is an initialism that stands for lesbian, gay, bisexual, and transgender. In use since the 1990s, the term is an adaptation of the initialism LGB, which was used to replace the term gay in reference to the LGBT community beginning in the mid-to-late 1980s. Activists believed that the term gay community did not accurately represent all those to whom it referred.

I have this affliction where I abbreviate “lesbian, gay, bisexual, and transgender” as “gay BLT.” An affliction called hunger.

There was a story on the news about vermin in a restaurant. As part of the story, the film loop showed the menu of the place, which had listed “Soylent Green Omelet” (okay, harharhar) and then a “GBLT”. I only caught a quick glimpse of the dish description underneath, which clearly said “. . .gay bacon lettuce tomato. . .”

Anyway, at least the author is honest about his motivation:
 
In the beginning it was simple enough: LGB or GLB, depending on the gender of the person using it. (As with a tennis score, you tend to put yourself first.) Then along came the transgenders and suddenly we had LGBT—or as I’ve heard it called, the “Gay BLT.” But once it became a multi-layered sandwich, there was no stopping it. And the more it grew, the harder it became to swallow. And identify with. The more groups it represented, the further away from my experience it drifted.

If you add guacamole to a BLT, you make an LGBT.
