Brainrot Barbarian

Tyr has brain rot, both literally, in that hundreds of simulated years in VR games has given him irreparable brain damage, and in that he tells his mom to stop yapping at him whenever she asks about him getting a job, or a girlfriend....or doing anything that isn't inside virtual reality. Unfortunatly, he dies from brain trauma caused by chronic VR overuse. Fortunately, a wandering goddess arrived on earth, looking for new champions . Although in the past they have gone for a more quality focused approach, selecting one champion to be the shining hope of the future. However, that hasn't been working, so now, they have decided to go all in on quantity, and Tyr just barely meets the very, very low bar. Will Tyr be able to survive in this new, hostile world? Will he even realize he's in a new world, and not just a new game? Will he stop accusing everyone who tries to tell him that he's been reincarnated of being a larper?
