A guy that makes moves on women but has no idea that they are doing everything in their power to avoid him.
A group of ladies are hanging out by the bar, your friend the donkuistador makes his approach and you sit back and watch as the ladies try to wiggle away from this idiot, but he keeps his attack going strong...thinking that they love him.
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."
