McBoss 

The combination of 3 dollar menu items from McDonalds to make 1 ultimate sandwich. The 3 items include a McChicken, a McDouble, and value fries.

How To Make:
Lay the fries in a row on both sides of the chicken in the McChicken. Next you split the McDouble in half from the patties. You then stick the whole McChiken (which now has fries on it) inbetween the two patties.

Order From Top to Bottom:
Bun
Patty
Bun
Fries
Chicken
Fries
Bun
Patty
Bun

In short it is a McDank with value fries on both sides of the chicken.

I used to eat McDanks, until I tried a McBoss.

McBoss 

A supervisor/boss of a low-paying job that matches two or more of the following criteria: morbidly obese, obscenely overpaid and under-worked, ridiculously mean, and beyond lazy/lethargic.

Joseph was hired by the school district as a part-time middle school English teacher, but his salary was only $25,000 a year and he didn't get a raise for five consecutive years. His McBoss LaShonda on the other hand, was making $200,000 a year to do not even a quarter of the workload that he did, weighed in at 330 lbs of pure body fat, was a crazy psycho bitch, and she sat around at her desk all day shoveling a dozen big macs, a bucket of soda, and a drum of KFC down her throat, all payed for by your hard-earned tax dollars!
