Costbro 

How you refer to those friends who help you through life after divorce by sharing a Costco membership so you do not get withdrawal symptoms from not having a large enough jar of mayonnaise.... in reserve.

Bob’s Costbro, Jock, was the perfect match. They consumed broiled chicken, cole slaw, three bean salad, Frank’s Red Hot and toilet paper at the same rates. But the best is that Jock builds winter scenes of little log houses out of Qtips at the same rate that wax builds up in Bob’s ears.

Castbro

A straight male in the midst of a region generally populated by gay men. Said straight male usually plays up his heterosexuality to make it apparent to others/outsiders that he is not gay, sometimes resulting in bro-like behavior.

A: "The waiter at that restaurant on Castro Street was totally a Castbro. He did not set off my gaydar at all."

B: "It's too bad - he's kind of cute."
