McBluffin' 

pretending that you don't want anything from McDonald's when, in reality, you do.

Often, someone who is McBluffin' will refuse to order anything from the drive thru, then subsequently ask for "a bite" of whatever it is you are eating, and steal all of your fries. McBluffers should be called out before ordering so they are forced to fess' up.

*car pulls up to the ordering window*

McDonald's Intercom: Hi, welcome to McDonald's may I take your order?

John (to intercom): Yep, Just one moment.

John (to Megan): Hey Megan, what do you want?

Megan: I'm actually not hungry, nothing for me thanks

John: Pshhht whatever Megan you better order something I know you're McBluffin'! Last time you "didn't want anything" you ate all my sausage McMuffin!!!

Megan: ...fine I'll have a Big Mac meal

John (to intercom): Yeah I'll have one Big Mac meal, a 6-pack of chicken nuggets....

McFluffin 

A McFluffin is the combination of a McFlurry and a McDonalds muffin. The idea is to peel the muffin and place it in the cup of the McFlurry ( which fits perfectly ) poke your spoon through and muffin till you get half muffin and half ice cream. If you're feeling cheeky ask them to heat up the muffin so it's a bit softer and the chocolate slightly melts ( if it is a chocolate muffin ).

Mate I could so do with a McFluffin right now!

Bluffer Mcbluffenton 

A characteristic of a poker player who is a cheeky bluffer, and everyone at the table can see through his little antics. This player is typically coined this term and is ridiculed throughout the entire game with no mercy.

The bluffer mcbluffenton couldn’t hide from the wraith of the profiteer, and was then forced by his superiors to be the big blind for the rest of the game.

mr. mcfluffy disease

when you are itchy all over and not sure of the cause: when anything irritates your skin such as fabrics, pets, soaps and you keep scratching yourself and can't stop

This all started when I used a cheap generic fabric softener in the dryer. I forgot the name of it, but the word "fluffy" was in the name. Everyone in the household started itching and scratching the next few days. So now when anyone is scratching for any reason, they say " I think I have a case of Mr. McFluffy disease!!!!"
