On the beach 

a phrase that federal government contractors use internally to describe paid company employees that are awaiting a security clearance in order to engage in their assigned client project. Typically, either by choice or because they have no other option, they are doing very little useful work.

Damn, Fred hasn't done shit for 6 months because he's been on the beach.

sun on the beach 

Sounds like "son of a bitch". Used to avoid swearing by high schoolers. May have first been attested in the 1962 film, "Mr. Hobbs Takes a Vacation" starring James Stewart.

Mr Hobbs: "Let's go get some sun on the beach!"

(Some time later, his foreign maid quits because she can't tolerate his "swearing")
