I've always considered "sliders" and the idea of sliders as a burger "quickie". It's everything you want it to be, quick, dirty and when you're finished, people don't even notice anything's gone. But M:Brgr's perverse minds so fittingly named this a "threesome" - in what context though? One big burger orgy with three burgers, or three quickies with the same burger? This analysis has gone completely off, I'll stop. BURGER SEX.
