Grumping it

When you skip a tutorial in a video game, and get stuck or lost in something the tutorial taught. A reference to Arin (Egoraptor) of the youtube channel Game Grumps, who would always skip tutorials.

"Bro, you're grumping it! You shouldn't have skipped the tutorial."
"Ah, yeah, I grumped it."
