@West-Tex : Omg! Just looked it up. From Urban Dictionary:
"Despite sounding like an innocent night in "Pizza Night" refers to a night of sexual activities between three people, usually involving a combination of *Alcohol, *Cannabis and Pizza (*not essential). A traditional "Pizza Night" usually consists of 2 guys and 1 girl, the females back is then used as a table to rest the pizza during intercourse."
