Vaintenance 

Vain personal grooming in which people indulge - such as men having their backs waxed or women having decals applied to their toenails.

“I don’t want to date him cuz he goes to the gym everyday and spends more time getting ready than I do. “He’s high vaintenance!”

Maintenance Wank

When you're participating in nofap and you begin to over sexualise things, like apple pies and peanut butter sandwhiches, it's time for a maintenance wank. This keeps your inner sexual deviant at bay, while also reducing the amount of awkward boners you might experience.

Guy 1: "I keep getting stiffies when I see anything that vaguely resembles titties or a vagina, it's killing me."
Guy 2: "Mate, it's time for a maintenance wank. If you don't let off some pressure, your dick is going to take over."

Maintenance Cocktail 

Spirits generally mixed with some sort of fruit juice and normally consumed in the late morning and/or early afternoon to help alleviate a particularly nasty hangover. Standard versions include Vodka/Cranberry, Screwdrivers, left over Hard Seltzers, and of course the Danimal. Also known as a Breakfast Cocktail when in Maui, a Maintenance Cocktail is essential for anyone who needs to rally and is eager to start working on the next day’s hangover.

Dave: Woof, I think we went a little overboard on the Peach Daiquiris last night..

Yoko: That’s why I stuck with white wine all night like a boss.

Dave: Good for you. I need to screw my head back on with a Maintenance Cocktail. Pass me the Gin and Tang.

Percussive Maintenance 

The fine art of bludgeoning an electronic device in order to encourage it to work properly. Vigorous usage of this technique often renders said device permanently nonfunctional.

My goddamned monitor was flickering until I used some percussive maintenance; now it's totally dead and Help Desk is bringing me a new one.

maintenance call 

Periodic phone calls placed to one's significant other when out for a prolonged period of time (eg 4 hours or more) with friends. The periodic phone call is intentionally structured to prevent a blow-up or fight after the outing is concluded, which would invariably take ten times longer to resolve that the time to place a brief check-in call.

"Hey, let me put in a maintenance call to my woman, before we go into the bar."
