Acronym for Inflated Lat Syndrome. ILS is a primal threat/mating display observed in the human male. The ILS display involves the male human holding out it’s arms away from it’s body at approximately a 20-40 degree angle and then walking with a slow deliberate gait inorder to look more imposing to other humans. The posture is used primarily as a form of non-verbal communication such as a mating display to attract or impress females or as a defense or dominance posture to appear larger to a threat or to intimidate rival males.

ILS displays can be observed :
In the gym after an insecure male works out for 3-5 minutes.
On the beach when a single male approaches a group of females.
When a male enters a bar or dance club.
When a male is too scared to throw the first punch in a fight.
On the outside of mosh pits by the bouncer who’s had enough of sweaty punks bumping in to him.

The two states of being are as a human being, or a hungry ghost. Semi-regularly you need to ask yourself which you are. Sometimes it is human. Others, alas, it is hungry ghost.

The hungry ghost seeks validity outside of themselves. Someone pining for an indifferent ex is a hungry ghost. Someone who arrives alone at 6:30 on Saturday night to a pub is probably a hungry ghost. Obsessive checking of mobile phones, chat sites or networks are clear signs that one is a hungry ghost.

The best thing to do is just stay home and ride it out. Read a book. Find some good clean fun.

Invisible Lat Syndrome. Guys who walk around thinking they're the man. Their arms are spread so far out that you cannot see their latissimus dorsi.

I.L.S. or Imaginary Lat Syndrome is an ailment suffered by men who walk around with thier arms further away from their lats (latimus dorsi), the muscle on the side of thier torso, to create the illusion that their lats (and physiques) are much bigger than they are.

Instrument Landing System

It is used in aviation, typically on bad IFR days. I HATE using the ILS because there's no skill...

Some operators require a landing with ILS, and some European airports do too.

I prefer doing NPAs or RNAV approaches...

The ILS catches usually around the Mode C Veil - 30 to 50 NM from the airport.

Usually only Class B Airports have ILS systems, but some Class C airports have Cat I systems...

Invisible Lat Syndrome.

ILS stands for Instrument Landing System in aviation.

It is a ground based radio system to guide ILS equipped aircraft accurately down onto the runway, usually in bad weather. Most aircraft these days can land without a pilot utilizating the ILS.
