McFlashback 

The unusual return of a McFeeling from one week to a year following a meal at McDonalds.

Carlita: "Oh Raul I feel weak and I think I might pass out and/or shit myself. I think it's a McFeeling but I haven't had McDonalds in months!"

Raul: "Worry not Carlita, you are probably just getting a McFlashback. Enjoy the ride."

McFlashy Pants 

Someone who has too much underwear or butt crack showing. It can either be on purpose or on accident.

When my boyfriend sleeps, he is such a Mr. McFlashy Pants.
I am such a McFlashy Pants when I wear these hips huggers.
