Get the Beerio mug.
A drinking game in which all the participants (2-4) must consume an entire beer within the duration of a single Mario Kart race. The twist is that you cannot drink while driving. The winner is the first person to finish the race as long as they have finished their beer. If you finish the race without having finished your beer, you get last place by default, as you are a rule-breaking pussy.
Eric: "Bro, last night my homeboy Rainbow Jeremy and I were playing some beerio kart. That shit's such a good pre-game."

Anthony: "Dude, Rainbow Jeremy is such a poon. He never finishes his beer before the race is over. Wanna get baked and listen to some Jack Johnson?"

The day after drinking and you have the beer shits but your friends want breakfast. So you pour them a bowl of honey nut cheerios but instead of milk you shit in the bowl with your liquid beer shit.
Chad wanted breakfast after a long night of drinking. So me, being a good friend, gave him a nice bowl of Honey Butt Beerios.
