MiFi 

MiFi stands for "my Wi-Fi" and is pronounced as "my-Fi."

MiFi is a portable broadband wireless device that combines functions of a router, modem and access point usually about the size of a credit card.

Also known as a personal hotspot. MiFi was designed to simplify setting up of small local area networks (LAN), or an ad-hoc network. MiFi devices support up to five users and can also network Wi-Fi-capable devices including cell phones, digital cameras, notebooks, MP3 players and gaming systems. A MiFi device gets Internet connection almost anywhere with cellular connectivity.

I just got a MiFi hook up and it works great.

MiFi 

Possibly the best nickname in the world. Only a very special person will ever be called MiFi. She would have to be the best person in the world. She would be the smartest, most amazing friend ever. You can only call your true bestie MiFi. She would have to mean the world to you. So much that you would feel comfortable to call her this. She is so amazing, and you never want her to leave. She is a true friend. Nothing not ever moving across the world could change that.

MiFi is my best friend;The MiFi will always stick by my side; MiFi is magical.

Mother I'd fuck if no better option present

"Really? You don't want to bang Janice?"
"Not particularly, she's a total mifinbop. Janice isn't hideous but I'd rather try seeing if Molly will give me a shot, she's much cuter"

The Mifia 

A business that someone made, where 2 people copied it and made it a business where they would kill people, then blame it on the Mafia.

P1- "Did you hear how the Mifia was on the run for like 90 years before getting caught as skeletons"

P2- "Wow. That seems like a really stupid thing that kids would make up!"

P1- "It probably was!"

MIFID 

MIFID Acronym: Mother I'd Fuck If Drunk

Pertaining to a MILF who doesn't quite meet the "Stifler's mom" grade.

Ropey milfs that you would only sleep with after hitting the brandy (because you drank all the lager)

"You slept with Ryans mum? Man, she's a total MIFID, you must have been wasted! Was she good?"

"I can't remember."
