Slang used in Robert Heinlein's classic Novel Starship Troopers (First published in 1959) to describe enemy aliens that were human like but thin and about 8 feet tall.

The novel is read and held in high regard by many soldiers. The term "skinny" is most popular for its usage in Mark Bowden's best selling book and later movie, Black Hawk Down. The Rangers referred to the Somalis as "skinnys" because they had read Starship Troopers.

(adj.) Having a lower amount of bady fat than the average in whatever country or province you happen to be in. Many women and tenage girls envy this quality, maybe because of the many problems that can be caused by being overweight and the increase in overweight and obese population in the world.
People who are 'skinny' are sometimes frowned upon. Girls who come naturally with this trait, probably by way of a high metabolism, are normally rather proud.
Needless to say, more extreme versions of this trait are dangerous and unhealthy.
Crazy teenage guy #1 who gets intoxicated every twelve hours: Dude, that girl is so skinny!

Crazy teenage guy #2 who gets intoxicated every twelve hours: Yeah. I bet she's anorexic or summit.

*Teenage girl approaches guys*

Teenage girl: I'm sick and tired of you stupid jerks insulting me every day because of my weight! I know I'm underweight and I've increased my calorie intake so you two can just shut the **** up!

*Girl runs away in a fury*

Crazy teenage guy #2 who gets intoxicated every twelve hours: ...did that just happen?

Crazy teenage guy #1 who gets intoxicated every twelve hours: No, man. Hey, let's go get wasted!

Very thin, lacking flesh. Something far too many women want to be, and incorrectly assume that this makes them desirable to men. Men often desire a fleshier woman.
Man, look at that skinny girl! You can make out where all her ribs are, and she's got no boobs or butt!

everyone chick wants to fucking be skinny
no one will deny it
it makes you feel great
and everyone will compliment you
you'll feel like a queen

but don't be a stupid ass retard
and develop a disorder, i use to be this
way and whenever i was starving i'd love
it because i felt skinny, but no really
it helps and is way more effective if
you're doing cardio and pilates, you'd
build strength and your muscles come out
more and plus you're not tierd and weak
all the time, so don't be fukcing stupid

go fucking work out, and sweat, and if
you're a fatass who cant do that much and
its already too late, then be happy with
yourself and don't make being skinny and
beautiful YOUR LIFE, be fucking confident
im not skinny BECAUSE im 5'2 and 124lbs,
