Get the o roberts mug.by SenpapitoesJ November 19, 2020
Get the o woa mug.The glorious Model O is the main mouse for every single 20 year old male who plays hypixel bedwars for a living. The mouse gives you an instant autoclicker and its a pretty neat mouse. Its also super light so you can throw it at ease. (you week mf) the O stands for "Oh my god I've never touched grass before" and the mouse looks like it was pulled out of a bee hive.
