A portmanteau of "poor
man" and "portmanteau". Signifies a word that is a feeble attempt at creating a portmanteau or a feeble attempt at
slang in general. It arises most often when someone consciously tries to come up with a
slang word or phrase.
The linguistics
professor knew much about language, but the
slang he came up with was riddled with poormanteaus.
"Poormanteau" is
clearly a poormanteau, and perhaps the only meta-poormanteau.
