"Make(s) your tongue slap your brain(s) out” means that something is mighty fine cooking. The jocular food expression is used in the South and has been cited in print since at least 1959.
29 September 1959, Baltimore (MD) Afro-American, “Meet Dr. Williams, Cook: He’s a college president who makes tasty barbecue” by Elizabeth M. Oliver, pg. 30, col. 6
AS THE FOLKS sitting around his table say: “The president’s hot barbecue’ll make your tongue slap your brains out, it’s that good.”
Dr. Williams himself is quite proud of his open pit cooking.
(Dr. John T. Williams of Maryland State College—ed.)
