The amount of brews (drafts) it requires to mac a certain biddy. If the chick is on the uglier side, she will be higher on the brewski meter, meaning that a bro would need to drink more beers in order to respectively mac. If the bid is a complete babe then a sober bro will suffice.
TDog: "Yo Chaz, how high is this chick on the brew meter?" Chaz: "She might take around three cold brewski's to chafe the biddy." TDog: "Thanks Bro"
