a JAYU is that type of mario kart player that plays the most horrid and tedious categories in the game just to gain a spot in the average finish leaderboard of the Player's Page.
JAYU is typically ignorant and insultive to every non-flap player and every Player's Page hater.
legend says that he is very racist and transphobic, even though very little evidence came out in the public chats. JAYU got banned from several discord servers and he is currently in rehab for his flap addiction.
