colin i may prefer smash burgers as food but it really must be said its the least fuckable kind of burger going on. it is flat. Sir Mix-A-Lot did not get knighted for us to fuck flat burgers
depends on your junk and size imo; some folks are gonna want a white castle slider and others are gonna be lookin for one of those instagrammable burgers that's a foot tall and impossible to fit your mouth around. the world is a beautiful and diverse place to a fuck a burger.
i can maybe give some concession here so long as appropriate lubrication is going on here- mayo, ketchup, mustard, perhaps the right kind of relish. a good smash burger has enough texture you're going to need it
