Pack Opener
A Pack Opener is someone who spends all their money on random loot just to get better, even though they're a complete noob at first. It's like throwing darts blindfolded and hoping for a bullseye.
My cousin opened 50 packs and still can't beat me at Fortnite.
He spent $100 on packs and got a rare skin. I got a trashy hat.
She opened packs for 3 hours and still didn't know how to play the game.
