The act of two flat arse people putting their arse up to one another during sexual intercourse and farting into each other's arse WHILST holding a lighter between both backsides and banging arses together.
*man walks into the bathroom while his roommate is showering*
"WTF man! What happened to your arse cheeks?!?!?"
"Oh, yeah, I was fucking that chick I've been going at it with last night and shit got kinky quick and we did the Spicy Sandanda and the lighter mixed with the farting burnt all my arse hairs off and I now have 2nd degree burns"
Hey, I'm a guy. I'm single. I would never cheat on you. I would always text you first, tell you that you're beautiful every day, say I love you in front of my friends, never choose my video games over you, protect you, try my best to never make you cry, hold you and never let you go, kiss you in the pouring rain. Yes, ladies, I do exist. No, I'm not gay. Stop dating douche-bags and jerks. Date me.
