expand dong 

To edit the text in an image and rearrange the letters to spell a nonsensical and often sexually suggestive/explicit phrase. Similar to the recurring gag that appears in the children’s book series “Captain Underpants”, but more risqué. The original “Expand Dong” was morphed from text found on the box cover of Donkey Kong 64.

sbubby is a variant of Expand Dong that focuses on corporate logos.

That “Thicc Mints” image is one of the best examples of expand dong that I’ve ever seen.

Expanding Family Syndrome

the annoying tendency of family groups in stores and other public places to spread out and block access for other shoppers or patrons. seen more often during the holiday shopping seasons, but can occur at any time. EFS can cause unsuspecting people to be forced hard against walls, merchandise displays, etc., or to have to detour around the family group to get at something of interest. similar to groups of aircraft, families often spread into various "vee" formations, echelons, and the dreaded "random EFS," past which nothing can pass, not even light.

this past christmas while shopping at a well-known discount department store, i was accosted by a family of four walking in a row across the aisle. as i was checking out items to purchase, the family came upon me, the dad saying "excuse us," as if i had anyplace else to go. i chose to stand my ground, causing the mom to glare at me and the family to pass me single-file. in this manner i prevented an outbreak of Expanding Family Syndrome.

Expand Dong 

1. To face the difficulties life has to bring and look back to those troubles as a lesson and/or a build of strength

2. To grow or progress on something potentially large

1. I used to think Honors Physics was hell, but no matter how much of hell I thought it was, I continued to try and get through everything it had to offer. I thought of some better study methods, learned what review processes work best for me, and it became way less of a struggle for me. In other words, beginning my destination to a Ph.D in Physics, I had to Expand Dong.

2. America's 19th century belief in a Manifest Destiny, the belief that Expansionism out west was justifiable and inevitable, required America to Expand Dong, and work hard to put everything the west had to offer to some good use.
