An addition to my other definition.
The duo has broken and repaired, but instead of Jon, Danny from NinjaSexParty joined. Fans are not pleased.
RubberRoss has also started a series with Danny on the Game Grumps channel as well, known as Steam Train. Instead of console games, the content it has is of computer games.
Ah man, Danny can never replace Jon in our Grump hearts!

Dude, Danny is a good addition to Game Grumps.

Litrally the best show you will EVER WATCH! They are so funny, quirky, adorable handsome men who over 5.2 million people love and do not dispize. There are, however, fan fiction of them. Which I personally like some. I'm not gonna name them though. They started in 2013. Then escalated out of no where and became very big. Now today, they are known worldwide, and most do like and enjoy their show.
The world: WE ♡ U GAME GRUMPS!!!
Game Grumps: Aww thank you :)

Playing an incredibly popular video game, often for hundreds of hours, and learning nothing whatsoever.

This can either dramatically lower your enjoyment, or raise it far higher than it should be.
"I just played Blank for the past week! It was so much fun!"
"Nice! What did you think of Story?"
"What? Oh I don't give a shit. I was just Game-Grumping."

A shit that takes a painfully long time to be had, possibly due to complications from previous bowel issues
Man, it took me over a hour on the can last night, after the first 20mins I knew I was having a Dirty Grump!

A let's play duo of Jon Jafari, or JonTron, and Arin Hanson, or Egoraptor. The channel has gained a large fanbase, and unlike other Let's Play channel fans, they are more accepting and do not rage if someone hates them. Games they have played are, to name a few, Goof Troop, Sonic the Hedgehog 2006, Castlevania 3, and Mega Man X7.
Game grumps is the greatest thing ever conceived!

Nah, I don't like it.

Whatever.
