Definition 1:
It is a a misnomer or bastardization of "the collapse". Which comes from World Wars when gonorrhea was so prevalent among GI's. It was in the hospital wards where the soldiers were that the medics and other patients would refer to it as "the collapse". Which through man's insufferable need to makes things smaller and easier because they are lazy, putrid, and even at the risk of endangering themselves, ignorant, shortened the word to "the clap".
Definition 2:
The term comes from the Paris neighborhood Clapier because of it's large number of prostitutes, or whores/hoes during the 14th century. And the word "clapier" might also have been another way of saying brothel or whore house, slut barn,pussy shack, or your mom's box, because of the prevalence of gonorrhea.
#1: A wounded soldier to a nurse changing a bedpan:

" What's wrong with that guy over there?"
Nurse:
" Oh, him? Oh, he's got the clap from one of those gook* hookers." * No offense to any Asian's who read this. I am not racist I just put it into context.
#2: I am too stoned to come up with an example of the second definition. Be lucky you got this much.
