1. When one of McDonald's foods, drinks, products etc. somehow invades the public in a way that says, "I'm lovin' it".

2. When you feel sick after eating something from McDonald.
1. I'm walking down the road one day and I see a Ronaldmobile drive by...you know a Mctack is coming.

2. After eating two Big macs, drinking two cokes, and 3 medium orders of fries, I think a Mctack is going to happen.

Stealthie 

when you're holding up your phone and making faces at it, as though you are taking a selfie, but you're really taking a picture of the person across from you or the wall or anything else that seems interesting but you don't want to be caught dead taking a picture of.

This action is often made more convincing by wiggling the eyebrows or opening the mouth, to pretend you're trying to get a Snapchat filter to work.
FRIEND A: "Did you just take a stealthie of me?"

FRIEND B (turning phone around): "no I was just using snapchat's new filter, see?"
