Get the in the sixmug. I could have bought a double double or a three by three, but I instead opted for the six by six because I'm hungry and hardcore

Get the six by sixmug. A huge burger from In-n-Out (a western US chain) comprised of 6 patties of meat and 6 slices of cheese. See "double double" and "four by four".
"Welcome to In-n-Out, may I take your order?"
"I'll have a six by six and a vanilla shake."
"That'll be $7.50, fattie"
