sixty-six 

When you want to subtly tell someone to look behind themselves, you tell them to check their "6 o'clock".
When you're trying to tell someone to look at someone behind someone behind them, you say "check your sixty-six".

"Bro, check your sixty-six."
(he looks behind himself)
"Meh, I'm not into blondes."
"I said sixty-six. The girl behind the blonde is a redhead."
