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.

When an individual becomes infatuated with their own reputation and creates a faux following and ego around themselves. This is all undone upon the individual visiting a larger town or city, where they find themselves somewhat unknown and ignored.

More commonly known as I.A.S., those who are afflicted with Intermittent Asshole Syndrome are known mainly by their lack of a filter between the things they think, and what actually comes out of their mouths. I.A.S. is in the "Foot in Mouth Spectrum" of disorders and is highly contagious.
Once encountered, I.A.S. can take weeks or months to become evident or it may have acute onset, taking only moments. Sufferers are cynical, critical and vindictive on an intermittent basis. The sydrome is fairly common among management personnel and security and law enforcement officers. Intermittent Assholes are generally very likeable, fun-loving and sweet people. Alcohol typically intensifies symptoms. Some people with I.A.S. believe themselves to be very funny, and infact some truly are. Contact with customers or the public in general tends to exacerbate symptoms and increase the frequency and intensity of outbreaks.
True sociopathic behavior is not associated with I.A.S..
Treatment is still in development.

Sorry I cracked a joke when you told me something personal and expected me to take you seriously. My Intermittent Asshole Syndrome has been acting up

The awkward stance that some males take in order to swell their chest in a ridiculous attempt at make non existing muscle seem present. Generally, the arms are lifted away from the body as if huge lat muscles were pushing them away. The author thinks that looking wide is the same as being wide and believes women will not see the difference.
Dave: Look at that skinny dude over there, he has no muscles but he is swelling himself up like a peacock!
Steve: Yeah he's got invisible lat syndrome, or ILS, common among douchbags who are too lazy to workout for their muscles!
