In a bowl, mix mayonnaise with ranch seasoning and chopped bacon to make the crack sauce.
Form ground beef into 4 patties and season both sides with salt and pepper.
Heat olive oil in a skillet over medium-high heat and cook patties for about 4 minutes per side, until browned.
Place a slice of cheddar cheese on each patty and let it melt.
Toast burger buns lightly in the same skillet.
Spread the crack sauce on the buns, then layer patties, lettuce, tomato, and pickles as desired.
Serve immediately while warm and melty.
