Halfstack 

Derived from the address "555 1/2 W Holland St.", along with a half stack amplifier metaphorically speaking, the Halfstack is the most amazing bachelor pad in the southeast region of South Dakota. Business offices below the apartment share the address "555 W Holland St.," thus the partial "1/2" comes into play. Apartment tenants go by the names "Josh" and "Kyler."

Dude, we gotta go to the Halfstack for a good jam session!

In verb form:
Joe is Halfstacking it up with his buddies.

Needle in a Haystack 

(figure of speech) referring to something small that is difficult to find in a large space, it quite literally would be like searching for a needle in a haystack, obviously nigh impossible.

Finding your dick to take a piss must be like finding a needle in a haystack.

Possum's Haystack 

n: The gnarliest, nappiest, most tangled thicket of pubic hair known to mankind.

Many different species of animals may inhabit the possum's haystack, because of the multiple ecosystems grown over time.

Nobody really knows how people become inflicted with the possum's haystack, however, experts do believe that it could possibly obtained from little to no maintenance to the "under rug" for many, many years. The condition, however, is fatal.

Reginald M. Nooker was the most famous case of possum's haystack. He did not trim his pubic hair for 39 years. His hair follicles were so overactive that they did not grow long, but thick, and tough, and they curved back and around in every possible direction. He broke many chainsaws simply trying to find his penis.

mouse on a haystack 

Picture of a nude man with his small penis sitting on top of his hairy scrotum.

Mike Clark liked to laugh at pictures of men modeling nude. If they had a small penis and a hairy scrotum, he would say that their package looked like a " MOUSE ON A HAYSTACK ".

halfbacker 

A person who originated from the Northeastern region of the United States (where it is commonly very cold and overcrowded), moved to Florida (where it is commonly very hot and overcrowded) and subsequently moved half-way back to the Northeast in hopes this unexploited region would provide cheap lobor and moderate weather. It seems their final choice in residence depends heavily on the route they took during their original migration to Florida, as the majority of halfbackers reside within a short drive of I-75, I-24 and I-81. Halfbackers often exhibit distinguishing traits such as the formation of densely populated communities, cultivation of foliage indiginous only to Southern Florida and an ironic nostalgic view of life in both Florida and the Northeast.

It's best not to argue with a halfbacker as they have seen much in their exstensive travels and are likely to be far wiser than you.
