Foyboy 

A male who avoids full intercourse and instead masters the many forms of non-penetrative sex. An accomplished muffer and expert in the art of joint masturbation.

“Yes mate, did you bang that bit of trim last night?”

“Naaaah, I was too hammered so I Foyboyed her this morning and got a taxi home”

Foyerism 

n. 1. Similar to voyeurism, foyerism is the compulsion some people have, when invited to a party, to remain in the area immediately adjacent to the entrance and just watch everyone else.

John came to the party, but never got more than 10ft from the front door. I think he may be into foyerism.
