McFlashback

The unusual return of a McFeeling from one week to a year following a meal at McDonalds.

Carlita: "Oh Raul I feel weak and I think I might pass out and/or shit myself. I think it's a McFeeling but I haven't had McDonalds in months!"

Raul: "Worry not Carlita, you are probably just getting a McFlashback. Enjoy the ride."

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!
