mananagement 

When a manager says they will do something the next day, but ultimately never do it. Combination of the words manana and management.

I keep asking mananagement to fire the creepy old guy or at least tell him to stop hitting on me, but they never do.

Mancentage 

When Men pull percentages out of thin air with no basis or sources.

"I heard 60% of people wait till getting out of their car to turn it off."
" That's a MANCENTAGE, you made that up."
