M.R.A.M 

We are all familiar with different types of computer RAM. Like EDO,DDR, and SDRAM.

MRAM is your Masturbation Random Access Memory. Something you store and save to be called on for later use.

"Whoa did you see that chick?! I'm going to shove her in my MRAM for later."

M.R.E. 

The M.R.E.'s are a vacuum packed high calorie food pack that contains enough food for one meal . M.R.E.'s are so disgusting that they are known as three lies in a bag . Also the inspiration for Ranger cooking .

Private Pile took the crackers and chocolate mix from his M.R.E. and made some ranger pudding.
