Well I just looked up lurgy on the Online dictionary of playground slang:
"lurgi, lurgy n. imaginary sickness that 1) girls had and you contracted by kissing them. 2) you had as a matter of course from being smelly or dirty or not like the other kids
The imaginary disease of the lurgi could also be spontaneously developed by someone in order to start a game whereby the afflicted child had to pass it on to someone else by touch. Other children could protect themselves by calling "injected!" and miming using a syringe in their arm. The word originates from an episode of the British 50s radio programme The Goon Show. The episode was called "Lurgi Strikes Britain", telling the story of an epidemic of the fictitious disease - and 45 years later the word is used universally across British schools by children who have never heard of the Goons., cf. injectified, cooties circa. 1950's onwards UK"
I think this site is made my a man.... because only boys have the lurgy!!!
I even looked up cooties... can you tell I am putting off doing an essay?
:"cooties n. Initially introduced as a bug - probably head lice, cooties are some form of horrid affliction that you can get by coming into contact with anyone of the opposite sex, or sometimes same sex, if they're gross. (i.e.: all gross people by definition have cooties.)
So once established as an imaginary infestation on the playground, cooties have become to be associated almost exclusively with with girls (possibly because they traditionally have more hair for head lice to infest) although anyone of questionable hygene is subject to cootie ridicule. Either way, for boys the rule is "Stay away from girls, because girl have cooties".
Infestation could be prevented by common measures like crossing your fingers (although in the US it wasn't called bargies) or simply by avoiding contact with infected persons(i.e. running away as fast as you can).
Also you could receive a cootie immunization by the well known incantation and actions:
"Circle, Circle, dot, dot,
Now I have my cootie shot"
(whilst drawing 2 circles on your forearm, and then poking it twice in the middle for the dot, dot part), I'm sure there is a lot more cootie lore out there. (ed: would love to hear it if you have some?) circa. 1940's+ USA "
The site I took these from is fantastic http://www.odps.org
