This is a meme-type joke, and the creator of this post is not sure if it is real, and physical, but in the meme world, it is one of the recent memes. It has many variations, ranging from making people infinitely gay, to making Pokemon bored. The character that is both a picture on most of these "Cards" and the namesake would be Gru, a character from the movie Despicable Me. Now, onto what the card actually does. The most common thing it does is reflect all No u's and make all players gay. As I have said before, there are multiple variations of it, but I cannot name them all.
Dude 1: Ur mom is gay
Dude 2: No u.
Dude 1: No u.
Dude 2: No u.
Dude 1: NO U!
Dude 2: I play the Gru card!
Dude 1:Noooo!
Dude 3: What are you guys doing?
Dude 2: *Whispers*
Dude 3: WHY AM I GAY?!
Dude 1 and 2 together: That's how it works.
Dude 2: No u.
Dude 1: No u.
Dude 2: No u.
Dude 1: NO U!
Dude 2: I play the Gru card!
Dude 1:Noooo!
Dude 3: What are you guys doing?
Dude 2: *Whispers*
Dude 3: WHY AM I GAY?!
Dude 1 and 2 together: That's how it works.
