An In n' Out burger with 6 pieces of meat and 6 pieces of cheese.
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

A hamburger from In-N-Out with 6 patties and 6 slices of cheese. Very tasty, very big.
"I want a 6 x 6, animal style, with grilled onions"

"Would you like fries with that?"

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"
