Mappainting 

Mappainting, also Map Painting, is a derogatory term to refer to gaming of Grand Strategy Games that are mostly painting maps, such as Hearts of Iron 4, The New Order: Last Days of Europe, Victoria 2, Europa Universalis 4, Stellaris, Sid Meier's Civilization series and similar games.

I love mappainting, but most people wonder how can someone find mappainting funny and entertaining.

Manprinting 

Manprinting is the act of smothering one's balls in ink for the sole purpose of later stamping an essay that is due the following day.

Manly Man: How can I ensure that my essay isn't stolen and plagiarized?
Less Manly but Thoughtful Friend: You could try manprinting it.
Manly Man: You're right! Good thinking. *proceeds to manprint his essay*
