Sumerian Footjob
Imagine the grimiest, dirtiest, sloppiest footjob of all time. This usually includes the added pleasure of several calluses and the cuts from overgrown toenails.
Mark: Yo Staysie, my girl gave me a Sumerian Footjob last night.

Staysie: How'd it go?

Mark: Yeah, but I'm pretty sure I have yellow fever now.
