A simple minded meathead. Similar in stature to the lummox, but not without positive qualities. Often kept in a group for the hi-jinx that his nature naturally brings about.
Meshes well with the dingus.

"Skittles. Wanna grab a fish taco?"

"Nah, but i bet you a foreskin that donkus grabs Darlas taco before we tuck in."

"Don't degrade women, Jessup."

Donkus is a word to describe somebody when they do a really stupid thing. It is commonly used against males, but it can be used against some females.

penis of above average size, that is used as tool to awake sleeping/passed out male friends and in some cases family members. A donkus is usually known all too well by the group of friends that it is associated with. Despite it's bad reputation and over-exposure it is an important part of the group dynamic and always "up" for a good laugh.
"Dude the Donkus woke up P-Dizzle again, I think P-Dizzle is starting to like it."

When you receive a dm from a girl asking for a dick pick and refusing. About an hour later she dm's your friend saying you were dating for a year, even though you have a girl friend, and you are also transgender.
This girl asked for a dic pic but it turned into a donkus poncus.
