Sidewards Taco 

Envision a taco full of horrific horse meat and mouldy salad. This terms pertains to the nastiest and most beat up of all vaginas out there, imagine a cross between Hitler's grandmothers corpse after it has been passed around a pack of hyenas and Tara Reid's snatch after a solid 4 hours of horse riding, minus the saddle. Safe to say the very entrance to hell is more welcoming a sight than a sidewards taco

David Cameron: Ohh bro I totally hooked up with Paris Hilton last night, but as I was going down to rainbow kiss her, I realised she had the worst sidewards taco ever and I had to bail!

Stalin: Bro that's weak man, why would you even think of going down on Paris?
