The cheap version of Big Mac from McDonald's. You basically order a Mcdouble ($1) and add big mac sauce and shredded lettuce. The shredded letuce should be an additional 20 cents for some dumb ass reason but basically you have yourself a big mac, without the middle bun. Only sexy people usually order this item.
