½ Man, ½ Chimpanzee. Most hilarious word ever. Too bad a Manpanzee doesn't actually exist, but there are many sightings of unidentified animals that could be a Manpanzee, like bigfoot, yeti, abominable snowman, etc. Also, the theync user weeg may possibly be a Manpanzee, judging from his speech patterns. A possible rendition of a Manpanzee is the infamous Mangurl, which is what weeg supposedly looks like.
Manpanzee can be affectionately shortened to Manpan. The female version of a Manpanzee would logically be Womanpanzee.
