Manhattan Project

Slang: a project which, over time, involves an increasingly large number of people and expense.
Origin: The US project during the second world war to devolop the Atom Bomb.

As they kept wanting more functions, more testing and documentation, what should have been a simple job turned into the Manhattan Project.

i urgently wanted to mount her, so I slipped her manhole cover to the side and pierced her lips rather than waste time peeling off her underpants

manheim township

the area in lancaster pa, where all the kids think they're the richest people in the world, even though their school is looking a lot like the local shit school McCaskey. where the fact that they acutally live in hicktown doesnt register in the minds and the fact that their highschool is finally on the verge of getting remodeled makes people angrier than ever.

Manheim Township is where people go to feel rich when it's really not that expensive to begin with.

manhunt surprise

When u drill a girl hard until she's ready to cum- you pull out and her hole remains gaping - and you stick your tounge way in there as far as you can to receive her gush of cream goodness.

Tom received a warm mouthful from lauren when he gave her a manhunt surprise during there one night stand in the back seat of his 69 cutless.
