The age old "hey it's me ur brother" scam.

The oldest version I heard of was in Japan in the 1990s. Scammers would call elderly people, claiming to be grandchildren, and demand money or they would be arrested/scandalized.

It was called the "ore ore" (pronounced "o-ray o-ray") scam because they would typically use the word "ore" for "I", a familiar and often brusque or aggressive form of the first person singular.
