McFishwich 

That sandwich at McDonald's purportedly made of "fish"...my guess is it is white rubber with mayo on bread. Also known as the Fillet-o-Fish.

Pick me up a McFishwich at Mickey-D's, I need to puke!

Someone new to the work environment whose sole purpose is to deliver lunch to the office.

Did the mcfish pick up the pizza yet?
Probably not. That mouth breather is so slow, and has feeble bones.
Typical mcfish

McFisty

To insert your entire hand into the vagina and/or anus of another whilst holding a McDonald's hamburger sandwich, most often a BIG mac but in essence, any hamburger sandwich from McDonald's extensive menu would constitute the act of McFisty.

Boy oh boy, this hamburger is causing acute sexual arousal, bend over. It's McFisty time.

big mcfish mac 

The "Big McFish Mac" is a custom burger created by the all mighty Jono. It's a regular BigMac with two Fish-O-Fish patties added to the burger.

It's a huge burger and a sickening sight to watch the master of it's creation slowly devour it.

If you want a Big McFish Mac then go to your local McDonalds and order a BigMac with 2 fish patties on it (don't let them remove the beef).

Holy f*ck that Big McFish Mac looks disgusting!
Hi, can I have a Big McFish Mac please?
