A secret phrase between two men at a social gathering or sporting event where they can alert the other that a chick with nice breasts is in the vicinity without alerting those around them. The term is simply boob minus an o. Boob-o=bob.
1st Dude: "Hey look there's Bob!" (Points at breast)
2nd Dude: "I am so glad he could make it. I was worried he wouldn't."
It's a catch phrase dating back to 1887, when, in a blatant case of favoritism, British Prime Minister Robert Cecil (a.k.a. Lord Salisbury) decided to appoint his nephew Arthur Balfour to the prestigious and sensitive post of Chief Secretary for Ireland.
So "Bob's your uncle" is another way of saying "your success is guaranteed."
You just put these parts together like this, and Bob's your uncle - you have a working model!
You want to go to the stadium? Go straight on until you reach the park, take the first left, and Bob’s your uncle - you're there!
And Means “there it is,” “there you have it,” or “everything is alright.” Commonly use in the UK and through the Commonwealth. Similar to the French “etviola.”
