The smaller brother (bro) of the McDonald's Big Mac. Instead of ordering the more expensive Big Mac ($3.25) spring for the Bro Mac which consists of the following: Double cheese burger off the dollar menu, add lettuce, add Big Mac sauce. This puts your Bro Mac at roughly around $1.60. Sure, it may not have the sesame seed bun, but it's still just as satisfying.
-"Yo after seeing that Big Mac commercial, I got the jonesn' for one of them jawns, but I'm running low on cash!!"

-"No worries man well swing by McD's and grab a Bro Mac, same stuff just mad cheaper!"
