(noun): this term, sister to muffleupagus, refers to a snatch that is boring. When you see it, your erection goes limp and directly into REM sleep (don't even try to "get it wet").
Angus: Hey man how'd it go with that freshman last night? You "get it wet"?
Wes: Hell nah man, that bitch had a muffasnoraus, put my shit right to sleep.
