Mousefishing 

Playing along with an obvious catfish for one's own amusement.

A fake Kendrick Lamar Instagram account DM'd me and is trying to Catfish me. I'm mousefishing him just to see what he'll say, this shit's hilarious.

mouseitis 

The condition resulting from using a mouse for so long, so often that your fingers and hand become numb, sore and even raw.

Awww, man, I've got mouseitis so bad I can barely do anything else with my right hand anymore.
