Doinking is trying to meet an objective that is most likely a waste of
time, such as placing a
square peg in a round hole.
Another situation you may find the word is when you are trying to create something out of what was seen as useless
junk beforehand.
Some times, what you create after doinking is called a jerry-rig.
I was doinking with my broken
computer when I realized I could use it to make an awesome
belt.
When you're doinking around with an open receptical, be sure to use a
plastic butter knife in the sockets and not a metal one.
