What is a singlet?

It's "a Word that isn't in the dictionary, but probably should be." This was made popular in the early 80's on the HBO show called Not Necessarily the News. Some sniglet examples are "Phenomeinumonemoneuminumoem" Which is the habit of looking into the mailbox after you dropped a letter into it to make sure it dropped into the box. Another one is "Khelgm" {kell-hmm} this is the dried up ketchup at the top of the ketchup bottle. A singlet is a mens or women's top that can be worn under other clothes or alone. it has thin straps (either spaghetti or tank)
