Left 4 Dead Syndrome 

Often caused by playing excessive amounts of Left 4 Dead games or any other zombie games. It is where you get to the point where you imagine what every place you go to would look like, if it were a zombie apocalypse.

Affected: Dude, imagine fighting off a zombie apocalypse in this mall! Aww man, you could even use that display car to escape.

Normal person: Wow, dude you've been playing way to much left 4 dead

Affected: Yeh, I think I've got left 4 dead syndrome

my mom is dead 

It can be something said after a "your mom" joke, but that doesn't mean it isn't true.
And it hurts more when your friend thinks that your just trying to make a comeback, and keeps going...

Jeff: Does your mom want her underwear washed with bleach or without?

Carl: My mom is dead.

Jeff: Should I wash the body, too?

Carl: *beats the shit out of Jeff*

The Dead Muskrat Clan 

The DMC for short. The Dead Muskrat Clan is a secret lifestyle dedicated to worshipping dead muskrats that have been shot twice in the head with a twelve-gauge shotgun. They sit on tree stumps and offer prayers as they give sacrificial offerings. These offerings, however, have to be red and also bloody.

Palm me a dead one

meaning to pass off a less than perfect item, either physical or metaphorical, as though it were good.

Example 1: I asked a friend to loan me a lighter but he palmed me a dead one. (Meaning the lighter didn’t work)

Its origin are uncertain but date back to at least the Childers Muster (Rodeo) of 1997 where it is attributed to Truckin' Trev.

The phrase has been bastardized to be used in circumstances with similar meanings to the original.

Example 2: My housemate said her friend would show me a good time but it turned out she was trying to palm me a dead one. (In this case it means the opposite of a “live one”, that is, the friend was boring or dull or frigid)

Example 3: The salesman said the DVD would play on all players but he had palmed me a dead one. (meaning that the DVD wouldn’t play or was blank)

Example 4: I asked my roommate to get me some milk for my coffee but she palmed me a dead one. (Meaning the carton/bottle was empty or out of date)

The phrase is not to be mistaken for any similar phrases use in the United States relating to slipping someone a bribe. That is palming someone a “dead president”, referring to the faces of dead presidents on the notes.

Whether it be bulbs, pipes, lighters, DVDs, food etc friends don’t palm friends dead ones. Ever!
