A McDonald's Big Mac that has had the middle bun replaced by a Filet-O-Fish patty. Also referred to as a Redneck Surf n' Turf.
My friend tricked me into eating a Fish Mac and I had to sit on the toilet for 2 weeks.

One of the types of sandwiches in McDonald's available IN EUROPE where you get a piece of fish instead of cow/pig meat in it.
There she was, pink clad, hair dyed stupid blonde, bolting Fish Macs one by one.

When you go to bed with a girl looking like a supermodel and you wake up the next morning her face on the pillow and she look hideous!

1.) A woman/man that applies makeup that is able to extremely alter their physical appearance so they appear more physically appealing than they actually are without makeup.
1.) My friend Kyle told me that he decided to take his date swimming for their 1st date to make sure she wasn't a MAC-Fishing/MAC-Fish underneath the pounds of makeup he seen she had applied to her face.

2.) Carlton was traumatized by Danielle after he woke up the next morning and walked pasted the mirror where she was standing. After seeing her face without makeup he thought to himself "I've got to get this woman away from me. She's MAC-Fishing/MAC-Fish. I will never get drunk and bring home another woman that wears MAC makeup or any makeup matter of factly."
