Macattack

The compulsive consumption of 3 or more McDonalds Big Macs in one sitting.

1. I had a Macattack on the way home after the football game.

2. We went to McDonalds and Nick had a total Macattack.

MacAttack

When you just ate an excessive amount of McDonald's, and you feel really gross and unhealthy.

Dude are you okay? You don't look too good...
Dude, I'm having a MacAttack. Why did we even get McDonalds ew.
