HBO Sex 

A particular kind of civilian love-making in the graphic/raunchy/loud manner we as viewers expect from such HBO shows as THE SOPRANOS, TELL ME YOU LOVE ME, THE WIRE and sometimes BIG LOVE.

BILLY: Hey, Susie, you sure are walking funny today.
SUSIE: You ain't whistling dixie, Billy. Me and that guy I met at Hyde totally had HBO Sex last night. I can barely sit down.
BILLY: Damn, you sure look it.
