SlumFuck 

The definition of SlumFuck is simple. Fucking in a place of filth or lower social standing. Case in point. An alley. A basement of an abandoned school. A shed filled with spiders. A crack house. You're mother in law's shitty nova. A trailer park. A porta john. A rest stop bathroom. An abandoned vehicle. Under an overpass. During a $5 dance at a strip club. Anywhere in Taiwan or Mexico. Fuck Mexico

Dan: John and Susan fucked in an alley!
May: Yeah! I heard they really got into the whole slumfucking stage in their relationship!
Dan: Weird..
