To be acting in a silly manner, especially so by completing a task in the least efficient, most idiotic way. Derived from the slang "mickey mousing", which was used to describe when someone would do something using the improper way, material, or method.

Yo guys I totally moused that math test, You just add denominators straight across, right?
Hey, sorry I can't come to the party tonight, I'm in a mousey mood.
Look here buster, you are one hair away from an ass whooping, so you better stop mousing it ASAP.

Mousing

When you take a handful of toilet paper but only wipe with you pointer and index fingers. This gives the palm something to grip, allowing for sturdiness and precision. This wiping technique feels as if you're scrolling a computer with a mouse. Just don't "click" too hard!

Janice, how are we going through so much toilet paper? We just bought a new pack a week ago...

Tim, relax. We haven't been going through that much..

Cindy, I've tried to get you to tell me the truth. I know you've been in there mousing!

Tweaking out or geeking out. A crazy state, typically induced by drugs or alcohol.

“This weed is making me mouse out so hard rn”

“Im going to mouse out if I get a 50% or lower on that math test”

“She’s mousing so hard rn because of my crazy dick”
